In the title complex, [Cd2Cl4(C6H12N4)(CH3OH)2] n , the hexamethylenetetramine (hmta) ligand is located on a twofold rotation axis and bridges four CdII ions through its four N atoms. Each CdII atom is coordinated, with a distorted octahedral geometry, by two N atoms from hmta ligands, two μ2-chloride anions, one terminal chloride anion and one methanol molecule. The μ2-chloride anions and hmta molecules link the CdII cations to form the three-dimensional polymeric structure. O—H...Cl hydrogen bonding between the methanol ligands and the terminal chloride anions is observed in the three-dimensional polymeric structure.

In the crystal structure of the title compound, (C5H6ClN2)[Cr(C2O4)2(H2O)2]·1.5H2O, the CrIII atom adopts a distorted octahedral geometry being coordinated by two O atoms of two cis water molecules and four O atoms from two chelating oxalate dianions. The cis-diaquadioxalatochromate(III) anions, 2-amino-5-chloropyridinium cations and uncoordinated water molecules are linked into a three-dimensional supramolecular array by O—H...O and N—H...O hydrogen-bonding interactions. One of the two independent lattice water molecules is situated on a twofold rotation axis.

In the title compound, [Cd(C2H8N2)3](GeF6), the CdIIatom, lying on a 32 symmetry site, is coordinated by six N atoms from three ethylenediamine (en) ligands in a distorted octahedral geometry. The Ge atom also lies on a 32 symmetry site and is coordinated by six F atoms. The en ligand has a twofold rotation axis passing through the mid-point of the C—C bond. The F atom is disordered over two sites with equal occupancy factors. In the crystal, the [Cd(en)3]2+cations and [GeF6]2−anions are connected through N—H...F hydrogen bonds, forming a three-dimensional supramolecular network.

There are three independent CdII ions in the title complex, {[Cd3(C10H3O8)2(H2O)4]·4H2O} n , one of which is coordinated by four O atoms from three 5-carboxybenzene-1,2,4-tricarboxylate ligands and by two water molecules in a distorted octahedral geometry. The second CdII ion is coordinated by five O atoms from four 5-carboxybenzene-1,2,4-tricarboxylate ligands and by one water molecule also in a distorted octahedral geometry while the third CdII ion is coordinated by five O atoms from three 5-carboxybenzene-1,2,4-tricarboxylate ligands and by one water molecule in a highly distorted octahedral geometry. The 5-carboxybenzene-1,2,4-tricarboxylate ligands bridge the CdII ions, resulting in the formation of a three-dimensional structure. Intra- and intermolecular O—H...O hydrogen bonds are present throughout the three-dimensional structure.

The title compound, poly[[diaqua-1κ2O-tetrakis(μ3-pyridine-2,3-dicarboxylato)-2:1:2′κ10N,O2:O2′,O3:O3′;2:1:2′κ8O3:O3′:N,O2-diiron(III)strontium(II)] dihydrate], {[Fe2Sr(C7H3O4)4(H2O)2]·2H2O}n, which has triclinic (P\overline{1}) symmetry, was prepared by the reaction of pyridine-2,3-dicarboxylic acid, SrCl2·6H2O and Fe(OAc)2(OH) (OAc is acetate) in the presence of imidazole in water at 363 K. In the crystal structure, the pyridine-2,3-dicarboxylate (pydc2−) ligand exhibits μ3-η1,η1:η1:η1and μ3-η1,η1:η1,η1:η1coordination modes, bridging two FeIIIcations and one SrIIcation. The SrIIcation, which is located on an inversion centre, is eight-coordinated by six O atoms of four pydc2−ligands and two water molecules. The coordination geometry of the SrIIcation can be best described as distorted dodecahedral. The FeIIIcation is six-coordinated by O and N atoms of four pydc2−ligands in a slightly distorted octahedral geometry. Each FeIIIcation bridges two neighbouring FeIIIcations to form a one-dimensional [Fe2(pydc)4]nchain. The chains are connected by SrIIcations to form a three-dimensional framework. The topology type of this framework istfj. The structure displays O—H...O and C—H...O hydrogen bonding.

In the title complex, [Cd(NO3)2(C20H14N4)2]·2H2O, the CdII ion, which lies on a crystallographic twofold axis, is bis-chelated by two nitrate ligands and is coordinated by one tertiary N atom from each of two 1,3-bis(1H-benzimidazol-2-ylmethyl)benzene ligands in a distorted octahedral geometry. In the crystal structure, complex molecules and solvent water molecules are connected via hydrogen bonds to form a three-dimensional network.

In the title compound, [Mn(C10H7N6)2(H2O)4]·2H2O, the complex unit comprises an Mn2+ion, coordinated by two imidazole N atoms fromcis-related monodentate 5-[4-(imidazol-1-yl)phenyl]tetrazolide ligands and four water molecules, together with two water molecules of solvation. The Mn2+ion lies on a twofold rotation axis and has a slightly distorted octahedral geometry. The molecules are connected by O—H...N and O—H...O hydrogen bonds involving both coordinated and solvent water molecules, generating a three-dimensional structure. Two C atoms of the imidazole ring of the ligand are each disordered over two sites with occupancy factors of 0.75 and 0.25.

The structure of the title salt, [CrCl(C10H8N2)2(H2O)][ZnCl4], has been determined from synchrotron data. The CrIIIion is coordinated by four N atoms from two 2,2′-bipyridine (bipy) ligands, one O atom from a water molecule and a chloride anion in acisarrangement, displaying a distorted octahedral geometry. The tetrahedral [ZnCl4]2−anion is slightly distorted owing to its involvement in O—H...Cl hydrogen bonding with the coordinating water molecule. The Cr—N(bipy) bond lengths are in the range 2.0485 (13)–2.0632 (12) Å, while the Cr—Cl and Cr—(OH2) bond lengths are 2.2732 (6) and 1.9876 (12) Å, respectively. In the crystal, molecules are stacked along theaaxis.

The asymmetric unit of the title complex, [Co(NO3)(C10H8N2)(H2O)3]Cl, consists of a chloride anion and a complex cation, which is built on a monodentate nitrate anion, three water molecules and one bidentate 2,2′-bipyridine molecule, coordinated to a CoII cation, in a distorted octahedral geometry. The water molecules are arranged in a facial geometry, and serve as donors for hydrogen bonding. Acceptor sites in the crystal are chloride ions and one O atom of the coordinating nitrate ion. A three-dimensional framework is formed, based on O—H...O and O—H...Cl contacts.

The tricationic charge of the complex is balanced by two bromide and one hexafluoridophosphate counter-anions. The compound crystallized with two molecules of dichloromethane (one of which is equally disordered about a Cl atom) and a water molecule. In the crystal, one of the Br anions bridges two water moleculesviaO—H...Br hydrogen bonds, forming a centrosymmetric diamond-shapedR42(8) motif. The cation and anions and the solvent molecules are linkedviaC—H...F, C—H...Br, C—H...Cl and C—H...O hydrogen bonds, forming a three-dimensional network.
