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.

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.

The tin(IV) atom in the complex anion of the title salt, (C4H7N2)[Sn(C2O4)Cl3(H2O)], is in a distorted octahedral coordination environment defined by three chlorido ligands, an oxygen atom from a water molecule and two oxygen atoms from a chelating oxalate anion. The organic cation is linked through a bifurcated N—H...O hydrogen bond to the free oxygen atoms of the oxalate ligand of the complex [Sn(H2O)Cl3(C2O4)]−anion. Neighbouring stannate(IV) anions are linked through O—H...O hydrogen bonds involving the water molecule and the two non-coordinating oxalate oxygen atoms. In combination with additional N—H...Cl hydrogen bonds between cations and anions, a three-dimensional network is spanned.

In the binuclear title compound, [Cu2(C8H4O4)Cl(C10H8N2)2(H2O)3]NO3·H2O, the two crystallographically independent CuII ions have similar coordination environments. One of the CuII ions has a square-pyramidal arrangement, which is defined by a water molecule occupying the apical position, with the equatorial ligators consisting of two N atoms from a 2,2′-bipyridine molecule, one carboxylate O atom from a terephthalate ligand and one O atom from a water molecule. The other CuII ion has a similar coordination environment, except that the apical position is occupied by a chloride ligand instead of a water molecule. An O—H...O and O—H...Cl hydrogen-bonded three-dimensional network is formed between the components.

The CoIIion in the title complex, [Co(SO4)(C13H8N4)(H2O)2]n, has a slightly distorted octahedral coordination environment formed by two O atoms from two symmetry-related bridging sulfate ligands, two N atoms from a bis-chelating 1H-imidazo[4,5-f][1,10]phenanthroline (IPL) ligand and two O atoms from coordinated water molecules. The bridging sulfate ligands connect CoIIions to form a one-dimensional chain along theb-axis direction. In the crystal structure, intermolecular O—H...O, O—H...N and N—H...O hydrogen bonds link the chains into a three-dimensional network.

The coordination chemistry of mixed-ligand complexes continues to be an active area of research since these compounds have a wide range of applications. Many coordination polymers and metal–organic framworks are emerging as novel functional materials. Aminopyrimidine and its derivatives are flexible ligands with versatile binding and coordination modes which have been proven to be useful in the construction of organic–inorganic hybrid materials and coordination polymers. Thiophenecarboxylic acid, its derivatives and their complexes exhibit pharmacological properties. Cobalt(II) and copper(II) complexes of thiophenecarboxylate have many biological applications, for example, as antifungal and antitumor agents. Two new cobalt(II) and copper(II) complexes incorporating thiophene-2-carboxylate (2-TPC) and 2-amino-4,6-dimethoxypyrimidine (OMP) ligands have been synthesized and characterized by X-ray diffraction studies, namely (2-amino-4,6-dimethoxypyrimidine-κN)aquachlorido(thiophene-2-carboxylato-κO)cobalt(II) monohydrate, [Co(C5H3O2S)Cl(C6H9N3O2)(H2O)]·H2O, (I), andcatena-poly[copper(II)-tetrakis(μ-thiophene-2-carboxylato-κ2O:O′)-copper(II)-(μ-2-amino-4,6-dimethoxypyrimidine-κ2N1:N3)], [Cu2(C5H3O2S)4(C6H9N3O2)]n, (II). In (I), the CoIIion has a distorted tetrahedral coordination environment involving one O atom from a monodentate 2-TPC ligand, one N atom from an OMP ligand, one chloride ligand and one O atom of a water molecule. An additional water molecule is present in the asymmetric unit. The amino group of the coordinated OMP molecule and the coordinated carboxylate O atom of the 2-TPC ligand form an interligand N—H...O hydrogen bond, generating anS(6) ring motif. The pyrimidine molecules also form a base pair [R22(8) motif]viaa pair of N—H...N hydrogen bonds. These interactions, together with O—H...O and O—H...Cl hydrogen bonds and π–π stacking interactions, generate a three-dimensional supramolecular architecture. The one-dimensional coordination polymer (II) contains the classical paddle-wheel [Cu2(CH3COO)4(H2O)2] unit, where each carboxylate group of four 2-TPC ligands bridges two square-pyramidally coordinated CuIIions and the apically coordinated OMP ligands bridge the dinuclear copper units. Each dinuclear copper unit has a crystallographic inversion centre, whereas the bridging OMP ligand has crystallographic twofold symmetry. The one-dimensional polymeric chains self-assembleviaN—H...O, π–π and C—H...π interactions, generating a three-dimensional supramolecular architecture.

The title compound, [Re(C8H6N4)(C25H22P2)(CO)3]CF3SO3·H2O, crystallizes with one [Re(C8N4H6){P(Ph)2CH2P(Ph)2}(CO)3]+cation, where Ph is a phenyl group, one CF3SO3−anion and one water molecule of hydration. The three C atoms of thefacialoriented carbonyl groups, two N atoms from the bipyrazine ligand and one P atom from the (bis)diphenylphosphanylmethane ligand define a distorted octahedral coordination environment about the central ReIatom. The Re—Ccarbonylbond lengthtransto the P atom is longer than the the two Re—Ccarbonylbond lengths in the plane with the bipyrazine ligand. Hydrogen-bonding interactions between the solvent water molecule and the cation, as well as weak C—H...O interactions, consolidate a three-dimensional network structure.

The synthesis of coordination polymers or metal–organic frameworks (MOFs) has attracted considerable interest owing to the interesting structures and potential applications of these compounds. It is still a challenge to predict the exact structures and compositions of the final products. A new one-dimensional coordination polymer,catena-poly[[[bis{1-[(1H-benzimidazol-2-yl)methyl]-1H-tetrazole-κN3}zinc(II)]-μ-hexane-1,6-dicarboxylato-κ4O1,O1′:O6,O6′] monohydrate], {[Zn(C6H8O4)(C9H8N6)2]·H2O}n, has been synthesized by the reaction of Zn(Ac)2(Ac is acetate) with 1-[(1H-benzimidazol-2-yl)methyl]-1H-tetrazole (bimt) and adipic acid (H2adi) at room temperature. In the polymer, each ZnIIion exhibits an irregular octahedral ZnN2O4coordination geometry and is coordinated by two N atoms from two symmetry-related bimt ligands and four O atoms from two symmetry-related dianionic adipate ligands. ZnIIions are connected by adipate ligands into a one-dimensional chain which runs parallel to thecaxis. The bimt ligands coordinate to the ZnIIions in a monodentate mode on both sides of the main chain. In the crystal, the one-dimensional chains are further connected through N—H...O hydrogen bonds, leading to a three-dimensional supramolecular architecture. In addition, the title polymer exhibits fluorescence, with emissions at 334 and 350 nm in the solid state at room temperature.
