A three-dimensional coordination polymer, poly[hexaaqua(μ4-glutarato)bis(μ3-sulfato)dineodymium(III)], [Nd2(H2O)6(glutarato)(SO4)2] n (glutarato2– = C5H6O4 2–), 1, consisting of cationic {Nd2(H2O)6(SO4)2} n 2n+ layers linked by bridging glutarate ligands, was synthesized by the microwave-heating technique within few minutes. The crystal structure of 1 consists of two crystallographically independent TPRS-{NdIIIO9} (TPRS is tricapped trigonal–prismatic geometry) units that form an edge-sharing dinuclear cluster interconnected to neighbouring dimers by the μ3-SO4 2– anions, yielding a cationic two-dimensional {Nd2(H2O)6(SO4)2} n 2n+ sheet. Adjacent cationic layers are then linked via the μ4-glutarato2– ligands into a three-dimensional coordination network. Strong O—H...O hydrogen bonds are the predominant interaction in the crystal structure.

In the title coordination polymer, [Ba(C5HN2O6)(C2O4)0.5(H2O)2]n, the tenfold coordination of the Ba centre consists of four O atoms from the two 4-nitro-2,5,6-trioxo-1,2,5,6-tetrahydropyridin-3-olate (L) anions, three O atoms of two oxalate anions and three water molecules. The Ba—O bond lengths fall in the range 2.698 (3)–2.978 (3) Å. TheLligand chelates two Ba atoms related by a screw axis, leading to formation of fused five- and six-membered chelate rings. Due to the bridging function of the ligands and water molecules, the complex monomers are connected into polymeric two-dimensional layers parallel to thebcplane. Intermolecular O—H...O hydrogen bonds link these layers into a three-dimensional supramolecular framework.

The polymeric title compound, [Cu2Br2(C4H8S)2] n , CP1, represents an example of a two-dimensional coordination polymer resulting from reaction of CuBr with tetrahydrothiophene (THT) in MeCN solution. The two-dimensional layers consist of two different types of rhomboid-shaped dinuclear Cu(μ2-Br)2Cu secondary building units (SBUs); one with a quite loose Cu...Cu separation of 3.3348 (10) Å and a second one with a much closer intermetallic contact of 2.9044 (9) Å. These SBUs are interconnected through bridging THT ligands, in which the S atom acts as a four-electron donor bridging each Cu(μ2-Br)2Cu unit in a μ2-bonding mode. In the crystal, the layers are linked by very weak C—H...·Br hydrogen bonds with H...Br distances of 2.95 Å, thus giving rise to a three-dimensional supramolecular network.

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.

In the title coordination polymer, [Dy2(C6H8O4)(C2O4)2(H2O)2]n, the asymmetric unit consists of one Dy3+cation, one half of an adipate anion, two halves of oxalate anions and one coordinating water molecule. The adipate and oxalate ions are located on centres of inversion. The Dy3+cation has a distorted tricapped trigonal–prismatic geometry and is coordinated by nine O atoms, four belonging to three adipate anions, four to two oxalate anions and one from an aqua ligand. The cations are bridged by adipate ligands, generating a two-dimensional network parallel to (010). This network is further extended into three dimensions by coordination of the rigid oxalate ligands and is further consolidated by O—H...O hydrogen bonds. A part of the adipate anion is disordered over two positions in a 0.75:0.25 ratio.

The three-dimensional title coordination polymer, {[Tb2(C8H2NO6)2(H2O)5]·H2O}n, was hydrothermally synthesized by reacting the corresponding rare-earth salt with pyridine-2,4,6-tricarboxylic acid (H3ptc). There are two independent TbIIIatoms in the structure, one of which is nine-coordinated, forming a monocapped NO8square-antiprism and the other is eight-coordinated exhibiting a 4,4-bicapped NO7trigonal–prismatic environment. The complex units are interconnected through the ptc3−anions acting in different coordination modes, resulting in a three-dimensional coordination polymer. The crystal structure features extensive O—H...O hydrogen bonds.

In the title compound, [Tb(C2H3O2)2(C11H10N4)(H2O)2]NO3·H2O, the Tb3+ ion is nine-coordinated in a distorted tricapped trigonal-prismatic geometry by the three N atoms of the tridentate 1-(pyridin-2-ylmethylidene)-2-(pyridin-2-yl)hydrazine ligand, four carboxylate O atoms of two chelating acetate groups and two O atoms of the coordinating water molecules. The organic hydrazine ligand is disordered over two orientations with a refined occupancy ratio of 0.52 (3):0.48 (3). All bond lengths in the coordination environment of the Tb3+ ion are slightly larger than those observed in the isostructural Y3+ and Er3+ complexes. In the crystal, the complex cations are linked by pairs of O—H...O hydrogen bonds into dimers. These dimers, nitrate anions and non-coordinating water molecules are joined by O—H...O and N—H...O hydrogen bonds into a three-dimensional structure.

In the two-dimensional title coordination polymer, [Zn(C8H4O4)(C14H14N4)] n , the ZnII atom adopts a distorted tetrahedral geometry, being ligated by two O atoms from two different benzene-1,3-dicarboxylate dianions and two N atoms from two symmetry-related 1,2-bis(imidazol-1-ylmethyl)benzene molecules. The dihedral angles between the imidazole rings and the benzene ring in the neutral ligand are 76.31 (13) and 85.33 (15)°. The ZnII atoms are bridged by dicarboxylate ligands, forming chains parallel to the a axis, which are further linked by 1,2-bis(imidazol-1-ylmethyl)benzene molecules, generating a two-dimensional layer structure parallel to the ac plane. The crystal structure is enforced by intralayer and interlayer C—H...O hydrogen bonds.

The rigid organic ligand (pyridine-3,5-diyl)diphosphonic acid has been used to create the title novel three-dimensional coordination polymer, [Ca(C5H6NO6P2)2(H2O)]n. The six-coordinate calcium ion is in a distorted octahedral environment, formed by five phosphonate O atoms from five different (pyridin-1-ium-3,5-diyl)diphosphonate ligands, two of which are unique, and one water O atom. Two crystallographically independent acid monoanions,L1 andL2, serve to link metal centres using two different coordination modes,viz.η2μ2and η3μ3, respectively. The latter ligand,L2, forms a strongly undulated two-dimensional framework parallel to the crystallographicbcplane, whereas the former ligand,L1, is utilized in the formation of one-dimensional helical chains in the [010] direction. The two sublattices ofL1 andL2 interweave at the Ca2+ions to form a three-dimensional framework. In addition, multiple O—H...O and N—H...O hydrogen bonds stabilize the three-dimensional coordination network. Topologically, the three-dimensional framework can be simplified as a very unusual (2,3,5)-connected three-nodal net represented by the Schläfli symbol (4·82)(4·88·10)(8).
