In the title coordination polymer,catena-poly[[bis[{1-[(1H-benzimidazol-2-yl-κN3)methyl]-1H-tetrazole}zinc(II)]-bis(μ4-pentane-1,5-dioato-1:2:1′:2′κ4O1:O1′:O5:O5′)] methanol disolvate], {[Zn(C5H6O4)(C9H8N6)]·CH3OH}n, each ZnIIion is five-coordinated by four O atoms from four glutarate ligands and by one N atom from a 1-[(1H-benzimidazol-2-yl)methyl]-1H-tetrazole (bimt) ligand, leading to a slightly distorted square-pyramidal coordination environment. Two ZnIIions are linked by four bridging glutarate carboxylate groups to generate a dinuclear [Zn2(CO2)4] paddle-wheel unit. The dinuclear units are further connected into a one-dimensional chainviathe glutarate ligands. The bimt ligands coordinate to the ZnIIions in a monodentate mode and are pendant on both sides of the main chain. In the crystal, the chains are linked by O—H...O and N—H...O hydrogen bonds into a two-dimensional layered structure. Adjacent layers are further packed into a three-dimensional network through van der Waals forces. A thermogravimetric analysis was carried out and the photoluminescent behaviour of the polymer was investigated.

Subtle modifications ofN-donor ligands can result in complexes with very different compositions and architectures. In the complexcatena-poly[[bis{1-[(1H-benzotriazol-1-yl)methyl]-1H-imidazole-κN3}copper(II)]-μ-benzene-1,3-dicarboxylato-κ3O1,O1′:O3], {[Cu(C8H4O4)(C10H9N5)2(H2O)]·2H2O}n, each CuIIion is six-coordinated by two N atoms from two crystallographically independent 1-[(1H-benzotriazol-1-yl)methyl]-1H-imidazole (bmi) ligands, by three O atoms from two symmetry-related benzene-1,3-dicarboxylate (bdic2−) ligands and by one water molecule, leading to a distorted CuN2O4octahedral coordination environment. The CuIIions are connected by bridging bdic2−anions to generate a one-dimensional chain. The bmi ligands coordinate to the CuIIions in monodentate modes and are pendant on opposite sides of the main chain. In the crystal, the chains are linked by O—H...O and O—H...N hydrogen bonds, as well as by π–π interactions, into a three-dimensional network. A thermogravimetric analysis was carried out and the fluorescence behaviour of the complex was also investigated.

The one-dimensional coordination polymercatena-poly[diaqua(sulfato-κO)copper(II)]-μ2-glycine-κ2O:O′], [Cu(SO4)(C2H5NO2)(H2O)2]n, (I), was synthesized by slow evaporation under vacuum of a saturated aqueous equimolar mixture of copper(II) sulfate and glycine. On heating the same blue crystal of this complex to 435 K in an oven, its aspect changed to a very pale blue and crystal structure analysis indicated that it had transformed into the two-dimensional coordination polymer poly[(μ2-glycine-κ2O:O′)(μ4-sulfato-κ4O:O′:O′′:O′′)copper(II)], [Cu(SO4)(C2H5NO2)]n, (II). In (I), the CuIIcation has a pentacoordinate square-pyramidal coordination environment. It is coordinated by two water molecules and two O atoms of bridging glycine carboxylate groups in the basal plane, and by a sulfate O atom in the apical position. In complex (II), the CuIIcation has an octahedral coordination environment. It is coordinated by four sulfate O atoms, one of which bridges two CuIIcations, and two O atoms of bridging glycine carboxylate groups. In the crystal structure of (I), the one-dimensional polymers, extending along [001], are linkedviaN—H...O, O—H...O and bifurcated N—H...O,O hydrogen bonds, forming a three-dimensional framework. In the crystal structure of (II), the two-dimensional networks are linkedviabifurcated N—H...O,O hydrogen bonds involving the sulfate O atoms, forming a three-dimensional framework. In the crystal structures of both compounds, there are C—H...O hydrogen bonds present, which reinforce the three-dimensional frameworks.

Distorted Octahedral Coordination Environment

In the title coordination polymer, [Cd2(SO4)2(C13H8N4)(H2O)2]n, there are two crystallographically independent CdIIcentres with different coordination geometries. The first CdIIcentre is hexacoordinated by four O atoms of four sulfate ligands, one water O atom and one N atom of a 1H-imidazo[4,5-f][1,10]phenanthroline (IP) ligand, giving a distorted octahedral coordination environment. The second CdIIcentre is heptacoordinated by four O atoms of three sulfate ligands, one water O atom and two N atoms of one chelating IP ligand, resulting in a distorted monocappedanti-trigonal prismatic geometry. The symmetry-independent CdIIions are bridged in an alternating fashion by sulfate ligands, forming one-dimensional ladder-like chains which are connected through the IP ligands to form two-dimensional layers. These two-dimensional layers are linked by interlayer hydrogen bonds, leading to the formation of a three-dimensional supramolecular network.

In the title coordination polymer, [Pb(C14H8N2O4)(CH3OH)2]n, the asymmetric unit contains half of a PbIIcation, half of a 2,2′-(diazene-1,2-diyl)dibenzoate dianionic ligand (denotedL2−) and one methanol ligand. Each PbIIcentre is eight-coordinated by six O atoms of chelating/bridging carboxylate groups from fourL2−ligands and two O atoms from two terminal methanol ligands, forming a distorted dodecahedron. The [PbL2(MeOH)2] subunits are interlinkedviathe sharing of two carboxylate O atoms to form a one-dimensional [PbL2(MeOH)2]nchain. Adjacent chains are further connected byL2−ligands, giving rise to a two-dimensional layer, and these layers are bridged byL2−linkers to afford a three-dimensional framework with a 41263topology.

Two novel symmetric fluorene-based ligands, namely, 2,7-bis(1H-imidazol-1-yl)-9,9-dimethyl-9H-fluorene [L1 or (I), C21H18N4] and 2,7-bis(1H-imidazol-1-yl)-9,9-dipropyl-9H-fluorene (L2), have been used to construct the coordination polymerscatena-poly[[dichloridodicopper(I)(Cu—Cu)]-μ-2,7-bis(1H-imidazol-1-yl)-9,9-dimethyl-9H-fluorene], [Cu2Cl2(C21H18N4)]n, (II), andcatena-poly[[tetra-μ2-chlorido-tetracopper(I)]-bis[μ-2,7-bis(1H-imidazol-1-yl)-9,9-dipropyl-9H-fluorene]], [Cu4Cl4(C25H26N4)2]n, (III). There are three types of C—H...N hydrogen bonds in (I), resulting a two-dimensional network in theabplane, including a chiral helical chain along thebaxis. Compounds (II) and (III) are related one-dimensional polymers. In both, CuIatoms connect the symmetric ligands (L1 orL2) into a one-dimensional chain. In (II), the {[CuICl2]−} unit, acting as a co-anion, adheres to the one-dimensional chain through a weak Cu...Cu interaction. However, in (III), the {[CuI2Cl4]2−} unit links two different chains into a one-dimensional rope-ladder-type chain. In addition, there are C—H...Cl hydrogen bonds and π–π interactions in the extended structures of (II) and (III), the difference is that the chains in (II) are linked into a two-dimensional network while the chains in (III) are stacked into a three-dimensional framework.

Each CdIIcation in the {[Cd(C8H15N2O2)Cl2]+}nchain is octahedrally coordinated by two pairs of bridging chloride ligands and two O atoms from different bridging carboxylate groups. CdIIcations in the {[CdCl3(H2O)]−}nchain are also octahedrally surrounded by four bridging chloride ligands, one terminal chloride ligand and one coordinated water molecule. Hydrogen bonds between solvent water molecules and these two independent chains generate a three-dimensional framework containing two-dimensional zigzag layers.<!?tpb=18pt>

In the title compound, [Co(C8H5O4)(C9H6N7)]n, the divalent CoIIatom is six-coordinated to three N atoms from two symmetrical 5-(pyridin-4-yl)-1H,2′H-3,3′-bi[1,2,4-triazole] (H2pyttz) ligands and three O atoms from three symmetrical 3-carboxybenzoate (Hbdic) ligands, leading to a distorted {CoN3O3} octahedral coordination environment. Two CoIIcations are linked by four bridging carboxylate groups to generate a dinuclear [Co2(CO2)4] unit. The dinuclear units are further connected into a chain along [010]viathe Hbdic ligands. The other infinite chain, along [100], is formed through the H2pyttz ligands. Finally, the two kinds of chains are cross-linked, by sharing the CoIIcations, into a two-dimensional network. In the crystal, adjacent layers are further linked by O—H...N hydrogen bonds into a three-dimensional framework.

A new Gd3+ coordination polymer (CP), namely, poly[diaqua[μ4-1′-carboxy-3,3′-(diazene-1,2-diyl)dibenzene-1,2,2′-tricarboxylato]gadolinium(III)], [Gd(C16H7N2O8)(H2O)2] n , (I), has been synthesized hydrothermally from Gd(NO3)3·6H2O and azobenzene-2,2′,3,3′-tetracarboxylic acid (H4abtc). The target solid has been characterized by single-crystal and powder X-ray diffraction, elemental analysis, IR spectroscopy and susceptibility measurements. CP (I) crystallizes in the monoclinic space group C2/c. The structure features a 4-connected topology in which Gd3+ ions are connected by carboxylate groups into a linear chain along the monoclinic symmetry direction. Adjacent one-dimensional aggregates are bridged by Habtc3− ligands to form a two-dimensional CP in the (10-1) plane. A very short hydrogen bond [O...O = 2.4393 (4) Å] links neighbouring layers into a three-dimensional network. A magnetic study revealed antiferromagnetic Gd...Gd coupling within the chain direction. CP (I) displays a significant magnetocaloric effect (MCE), with a maximum −ΔS m of 27.26 J kg−1 K−1 for ΔH = 7 T at 3.0 K. As the MCE in (I) exceeds that of the commercial magnetic refrigerant GGG (Gd3Ga5O12, −ΔS m = 24 J kg−1 K−1, ΔH = 30 kG), CP (I) can be regarded as a potential cryogenic material for low-temperature magnetic refrigeration.

In the title coordination polymer, {[Cd(C6H8O4S)(C13H14N2)]·H2O}n, the CdIIatom displays a distorted octahedral coordination, formed by three carboxylate O atoms and one S atom from three different 3,3′-thiodipropionate ligands, and two N atoms from two different 4,4′-(propane-1,3-diyl)dipyridine ligands. The CdIIcentres are bridged through carboxylate O atoms of 3,3′-thiodipropionate ligands and through N atoms of 4,4′-(propane-1,3-diyl)dipyridine ligands to form two different one-dimensional chains, which intersect to form a two-dimensional layer. These two-dimensional layers are linked by S atoms of 3,3′-thiodipropionate ligands from adjacent layers to form a three-dimensional network.
