In the title compound, [CdCl2(C13H12N4S)]·CH3OH, the coordination geometry of the CdIIion is slightly distorted square-pyramidal, as indicated by the τ index of 0.36 (8). The S atom, two N atoms from the pyridyl-azomethine moiety and one of the Cl atoms comprise the basal plane, while the other Cl atom occupies the apical position. The hydrazinecarbothioamide moiety adopts anEconformation with respect to the azomethine bond. The solvate molecule in the crystal lattice plays a major role in interconnecting adjacent molecules by means of O—H...Cl and N—H...O hydrogen-bonding interactions. A supramolecular three-dimensional architecture is sustained in terms of further N—H...Cl and C—H...Cl hydrogen-bonding interactions.

Trigonal Prismatic

The asymmetric unit of the title compound, [Ag3Yb(C5HN2O4)2(H2O)2]n, contains three AgIions, one YbIIIion, two imidazole-4,5-dicarboxylate ligands and two coordinating water molecules. The YbIIIatom is eight-coordinated, in a bicapped trigonal prismatic coordination geometry, by six O atoms from three imidazole-4,5-dicarboxylate ligands and two coordinating water molecules. The two-coordinated AgIions exhibit three types of coordination environments. One AgIatom is bonded to two N atoms from two different imidazole-4,5-dicarboxylate ligands. The other two AgIatoms are each coordinated by one O atom and one N atom from two different imidazole-4,5-dicarboxylate ligands. These metal coordination units are connected by bridging imidazole-4,5-dicarboxylate ligands, generating a two-dimensional heterometallic layer. These layers are stacked along theaaxisviaO—H...O hydrogen-bonding interactions to generate a three-dimensional framework.

In the crystal structure of the ruthenium(III) complex, trans-[RuIII(dcbpy)2Cl2]ClO4 (dcbpy = 2,2′-bipyridine-4,4′-dicarboxylic acid, C12H8N2O4), the RuIII atom lies on an inversion centre, showing a small distortion in its octahedral environment. The Ru—Cl bond lengths are shorter than those present in the analogous trans-ruthenium(II) compound containing the bipyridine ligand. The C—O distances in the two symmetry-independent carboxylic acid moieties of the ligand are similar in one group, but different in the other. This is probably due to the different intermolecular interactions they experience with neighbouring cationic complexes. The hydrogen-bonding interactions in which they are involved form a three-dimensional structure, similar to those found in coordination polymers.

The molecule of the title complex, [Ni2(C21H15N3O5)2(H2O)4]·4C3H7NO, is located on an inversion centre. This results in a dimeric NiIIcomplex, with the two NiIIatoms bridged by phenolate O atoms. The tridentate ligand is chelated to each NiIIatomviaone N and two O atoms of the iminolate form of the hydrazide moiety, which has the same conformation as the free ligand. The coordination geometry around each NiIIion is slightly distorted octahedral. A supramolecular three-dimensional architecture is created by dominant intermolecular O—H...N, O—H...O and C—H...O hydrogen-bonding interactions. These are augmented by two C—H...π interactions and a π–π interaction with a centroid–centroid distance of 3.681 (2) Å.

In the title complex, [RuCl2(C12H9BrN2)2] or [RuCl2(PM-BrA)2] (PM-BrA = 4-bromo-N-(2′-pyridylmethylene)aniline), the RuIIcation is located on a centre of inversion and is surrounded by four N atoms of two PM-BrA ligands in the equatorial plane and by two Cl atoms in atransaxial arrangement, displaying a distorted octahedral coordination environment. Two C atoms in the benzene ring of the PM-BrA ligand are equally disordered over two sets of sites. The benzene and pyridine rings of the PM-BrA ligand are oriented at dihedral angles of 62.1 (10) and 73.7 (11)° under consideration of the two orientations of the disordered benzene ring. In the crystal, the complex molecules are connectedviaC—H...Cl hydrogen-bonding interactions into a layered arrangement parallel (100). C—H...Br hydrogen bonding and weak aromatic π–π stacking interactions complete a three-dimensional supramolecular network.

Abstract Preparations, crystal structures, thermal properties, IR and UV/vis spectroscopic studies and magnetic moments of tris(1,10-phenanthroline)cobalt(II) squarate octahydrate, [Co(phen)3]sq ・ 8H2O (1) and diaquabis(picolinamide)cobalt(II) squarate, [Co(H2O)2(pia)2]sq (2) are described. 1 crystallizes in the monoclinic system, space group P21/c, with a = 10.9832(5), b = 21.4569(12), c = 17.0649(7) Å , β = 98.159(3)° and Z = 8, while 2 crystallizes in the triclinic system, space group P1̅, with a =6.9624(9), b =7.9224(11), c =8.0501(11)Å ,α =107.404°, β =93.340(11)°, γ =93.266° and Z = 1. Both 1 and 2 have slightly distorted octahedral coordination geometry, involving six N atoms from bidentately chelating phen ligands and trans-[CoN2O4] coordination geometry, in which the Co atom is located at a center of symmetry. There are significant hydrogen-bonding interactions in the structure of 1. The squarate dianions are linked to the eight solvent water molecules by means of hydrogen-bonding interactions. Moreover, there are links between the complex cation and the squarate dianion via C-H···O hydrogen bonds. These interactions hold the crystal structure of 1 in a three-dimensional network, while O-H···O, N-H···O, weak π ···π and π ··· ring interactions lead to a three-dimensional crystal structure for 2. The thermal decomposition pathways of 1 and 2 have been investigated by the help of thermal analyses data (TG and DTA).

In the title compound, [Cu(C7H4NO4)2(NH3)4], the Cu atom is six-coordinated by four ammine N and two 4-nitrobenzoate O atoms. Of the two nitrobenzoate ligands, one gives weaker coordination than the other. These Cu complexes are connected through a complex pattern of hydrogen-bonding interactions, resulting in a three-dimensional network.

The title compound, [CuCl2(C19H16N4O)], contains a CuIIatomN,N′,O-chelated by a neutralN-phenylhydrazinecarboxamide ligand and additionally coordinated by two Cl atoms, resulting in a distorted square-pyramidal geometry. The ligating atoms in the basal square plane of the complex comprise the azomethine N, the pyridine N, the amide O and one of the Cl atoms, whereas the other Cl atom occupies an apical position. The apical Cl atoms in adjacent layers function as hydrogen-bond acceptors to both NH groups. Intermolecular C—H...Cl and C—H...O interactions are also observed.

The title compound, {[Zn(C9H11N2S2)2]·0.5C6H7N} n , comprises two independent, but chemically similar, Zn[S2CN(Et)CH2py]2 residues and a 4-methylpyridine solvent molecule in the asymmetric unit. The Zn-containing units are connected into a one-dimensional coordination polymer (zigzag topology) propagating in the [010] direction, with one dithiocarbamate ligand bridging in a μ2-κ3 mode, employing one pyridyl N and both dithiocarbamate S atoms, while the other is κ2-chelating. In each case, the resultant ZnNS4 coordination geometry approximates a square pyramid, with the pyridyl N atom in the apical position. In the crystal, the chains are linked into a three-dimensional architecture by methyl- and pyridyl-C—H...S, methylene-C—H...N(pyridyl) and pyridyl-C—H...π(ZnS2C) interactions. The connection between the chain and the 4-methylpyridine solvent molecule is of the type pyridyl-C—H...N(4-methylpyridine).

The two title compounds, C8H6O2S6and C8H6O2S4Se2, are isotypic with very similar cell parameters. The complete molecules constitute the asymmetric units, despite being chemically perfectly symmetric. The most prominant differences in the metrical parameters arise from the distinct sizes of sulfur and selenium in the dichalcogenide bridges, with C—S—S—C and C—Se—Se—C torsion angles of 70.70 (5) and 68.88 (3)°, respectively. The crystal packing is determined by weak non-classical hydrogen-bonding interactions. One carbonyl oxygen but not the other participates in C—H...O interactions zigzagging along thebaxis, forming infinite chains. This is complemented by an intramolecular C—H...S interaction and further intermolecular C—H...S (C—H...Se) interactions, resulting in a three-dimensional network. The interactions involving the bridging chalcogenides form chains protruding along thecaxis.
