The bismuth(III) complex of thiosalicylic acid (2-mercaptobenzoic acid; H2L), ammonium tris(2-mercaptobenzoato-O,S) bismuth(III) dihydrate, {(NH4)3[Bi(L)3]·2 H2O}, has been prepared and its crystal structure determined. The distorted octahedral tris-bidentate complex unit has pseudo-C3 symmetry with the facially related thiolate sulfur donors providing a regular facial cap to the octahedron (Bi–S 2.595, 2.596, 2.596(5) Å) with the Bi–O(carboxylate) distances less regular (2.715, 2.741, 2.785(15) Å). The network polymeric structure is stabilized by hydrogen-bonding associations through both the ammonium counter ions and the lattice water molecules.

In the structure of the title complex, (C7H7N2S)2[Cd(C8H8O5)2]·6H2O, the CdII atom is located on an inversion center and is O,O′,O′′-chelated by two symmetry-related 7-oxabicyclo[2.2.1]heptane-2,3-dicarboxylate ligands in a distorted octahedral geometry. The 2-aminobenzothiazolium cation links with the Cd complex anion via N—H...O hydrogen bonding. Extensive O—H...O and N—H...O hydrogen bonds involving lattice water molecules occur in the crystal structure.

The title compound, [Co(C6H6NO3S)2(H2O)2] n , was obtained from a mixture of Co(NO3)2·6H2O and a previously synthesized salt, namely CyNH3·NH2PhSO3, in a 1:1 ratio (Cy = cyclohexyl; Ph = phenyl). The crystal structure consists of a three-dimensional supramolecular framework, in which polymeric layers are interconnected via N—H...O and O—H...O hydrogen bonding. The polymeric layers are formed by an interconnection of neighbouring cobalt(II) cations via NH2PhSO3 − bridges. Each cobalt(II) cation is surrounded by four NH2PhSO3 − moieties and two water molecules, leading to a distorted octahedral environment.

The crystal structure of the title compound, [Co(C6H4NO2)2(H2O)2]·2H2O, has been reinvestigated with improved precision [previous reports: Chang et al. (1972). J. Coord. Chem. 2, 31–34; Lumme et al. (1969). Suom. Kemistil. B, 42, 270]. In the title compound, the Co atom is located on an inversion center and its coordination can be described as slightly distorted octahedral, equatorially trans-coordinated by two N and O atoms of two picolinate ligands and axially coordinated by two O atoms of the water molecules. Intermolecular O—H...O and C—H...O hydrogen-bonding interactions result in the formation of an intricate three-dimensional network.

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 compound, [Fe(C10H15N2O2)Cl2]·2H2O, the FeIIIion is coordinated by two N and two O atoms of the tetradentate 2-{(2-hydroxyethyl)(pyridin-2-ylmethyl)amino}ethanolate ligand and by two chloride anions, resulting in a distorted octahedral coordination sphere. The average Fe—X(X= ligand N and O atoms) and Fe—Cl bond lengths are 2.10 and 2.32 Å, respectively. In the crystal, duplex O—H...O hydrogen bonds between the hydroxyl and ethoxy groups of two neighbouring complexes give rise to a dimeric unit. The dimers are connected to the lattice water molecules (one of which is equally disordered over two sets of sites) through O—H...Cl hydrogen bonds, forming undulating sheets parallel to (010). Weak C—H...Cl hydrogen bonds are also observed.

The crystal structure of the title compound, [Ru(C7H6N4)3](PF6)2·3H2O, a novel RuII complex with the bidentate ligand 2-(1H-imidazol-2-yl)pyrimidine, comprises a complex cation in the meridional form exclusively, with a distorted octahedral geometry about the ruthenium(II) cation. The Ru—N bonds involving imidazole N atoms are comparatively shorter than the Ru—N bonds from pyrimidine because of the stronger basicity of the imidazole moiety. The three-dimensional hydrogen-bonded network involves all species in the lattice with water molecules interacting with both counter-ions and NH hydrogen atoms from the complex. The supramolecular structure of the crystal also shows that two units of the complex bind strongly through a mutual N—H...N bond. The electronic absorption spectrum of the complex displays an asymmetric band at 421 nm, which might point to the presence of two metal-to-ligand charge-transfer (MLCT) bands. Electrochemical measurements show a quasi-reversible peak referring to the RuIII/RuII reduction at 0.87 V versus Ag/AgCl.

The synthesis of the title hydrated complex salt, [Co(C6H14N2)3]Cl3·H2O, from racemictrans-1,2-diaminocyclohexane and [CoCl(NH3)5]Cl2and its structural characterization are presented in this paper. The product was synthesized in the interest of understanding the hydrogen-bonding patterns of coordination complexes. Previous characterizations of the product in theI-42dspace group have not yielded coordinates; thus, this paper provides the first coordinates for this complex in this space group. The octahedrally coordinated cation adopts twofold rotation symmetry, with outer-sphere chloride counter-ions and solvent water molecules forming a hydrogen-bonded network with amine H atoms.

The crystal structure of the title compound, cadmium sulfate monohydrate or poly[(μ2-aqua)(μ4-sulfato)cadmium], was redetermined based on modern CMOS (complementary metal oxide silicon) data. In comparison with the previous study [Bregeault & Herpin (1970).Bull. Soc. Fr. Mineral. Cristallogr.93, 37–42], all non-H atoms were refined with anisotropic displacement parameters and the hydrogen-bonding pattern unambiguously established due to location of the hydrogen atoms. In addition, a significant improvement in terms of precision and accuracy was achieved. In the crystal, the Cd2+cation is coordinated by four O atoms of four sulfate anions and two O atoms of water molecules, forming a distorted octahedraltrans-[CdO6] polyhedron. Each sulfate anion bridges four Cd2+cations and each water molecule bridges two Cd2+cations, leading to the formation of a three-dimensional framework, with Cd...Cd separations in the range 4.0757 (2)–6.4462 (3) Å. O—H...O hydrogen-bonding interactions of medium strength between the coordinating water molecules and sulfate anions consolidate the crystal packing.

In the title complex, [Co(C6H5N2O2)2(H2O)2], the Co2+ cation lies on an inversion centre and the coordination geometry is distorted octahedral, with two N atoms and two O atoms from the 5-methylpyrazine-2-carboxylate ligands in the equatorial plane. The two remaining coordination sites are occupied by two water molecules. The crystal structure is stabilized by a network of O—H...O hydrogen-bonding interactions, forming a two-dimensional supramolecular structure.

The title compound, {[Cu2(C7H4O3)2(H2O)2]·2H2O}n, contains two copper(II) cations in special positions (one on a twofold rotation axis and one on an inversion centre) and the the salicylate ligand in its dianionic form. By four- and six-coordinate metal coordination, chains are formed parallel to [001], which are extended by O—H...O hydrogen bonding into sheets extending parallel to (100). These sheets are weakly connected by O—H...O hydrogen bondingviathe non-coordinating lattice water molecules into a three-dimensional network.
