    ABSTRACT: In the crystal of the title polymeric compound, [CdBr(CHN)] , the Cd cation is located on a twofold rotation axis and is six-coordinated in a distorted octa-hedral geometry formed by two N atoms from the 4,4'-dimethyl-2,2'-bipyridine ligand and by four bridging Br anions. The bridging function of the Br anions leads to a polymeric chain running along the axis. Weak C-H⋯π inter-actions observed between adjacent chains are effective in the stabilization of the three-dimensional packing.

    ABSTRACT: The asymmetric unit of the title compound, [InCl(CHN)(CHNO)]·0.5HO, contains two independent In complex mol-ecules with similar structures and one lattice water mol-ecule. In each complex mol-ecule, the In atom is six-coordinated in a distorted octa-hedral geometry, formed by two N atoms from the chelating 5,5'-dimethyl-2,2'-bipyridine ligand, one O atom from a dimethyl-formamide and three Cl atoms. In the crystal, the lattice water mol-ecule is linked to the complex mol-ecules O-H⋯Cl hydrogen bonds. Further weak C-H⋯Cl and C-H⋯O hydrogen bonds result in the formation of a three-dimensional structure.

    ABSTRACT: The title compound, [CdBr(CHN)], consists of a centrosymmetric dimeric unit in which two Br atoms bridge two Cd atoms, forming a four-membered ring. A terminal Br atom and a bidentate chelating 4,7-diphenyl-1,10-phenanthroline ligand complete a square-pyramidal geometry for the Cd atom. In the crystal, C-H⋯Br hydrogen bonds and π-π contacts between the pyridine and phenyl rings [centroid-centroid distances = 3.704 (4) and 3.715 (4) Å] lead to a three-dimensional supra-molecular structure.

    ABSTRACT: In the crystal of the title polymeric compound, [Cu(2)(SO(4))(2)(C(5)H(5)N(3)O)(2)(H(2)O)(4)](n), two independent Cu(II) atoms are located on individual inversion centers. One Cu(II) atom is coordinated by four water mol-ecules and two pyrazine-2-carboxamide ligands in a distorted O(4)N(2) octa-hedral geometry; the other is N,O-chelated by two pyrazine-2-carboxamide ligands and further coordinated by two sulfate anions in a distorted O(4)N(2) octa-hedral geometry. The pyrazine-2-carboxamide ligands bridge the Cu(II) atoms to form a polymeric chain running along [110]. The crystal structure features N-H⋯O, O-H⋯O and weak C-H⋯O hydrogen bonds.
