In the title compound, {[Cu(C14H8O4)(C4H6N2)2]·2H2O} n, each CuII atom is four-coordinated by two N atoms from two 2-methyl-1 H-imidazole (mi) ligands and two O atoms from two biphenyl-2,2′-dicarboxylate (dpdc) anions in a distorted square-planar coordination environment. Each dpdc ligand bridges two neighboring CuII atoms in a bis-monodentate mode, forming a zigzag chain along the b axis. These chains are decorated with mi ligands alternately on the two sides. O—H...O and N—H...O hydrogen bonds involving the water molecules link the chains together, forming a supramolecular structure. [ABSTRACT FROM AUTHOR]

The title compound, [Sn4(CH3)8(C6H5N2O2)4O2]·6H2O, is a hydrated cluster containing four Sn atoms, built up by inversion symmetry around the central Sn2O2 ring.

All the cluster non-H atoms, with the exception of the Sn-bonded methyl groups, lie on a mirror plane. Two of the water-molecule O atoms have m site symmetry; the other occupies a twofold rotation axis. [ABSTRACT FROM AUTHOR]

The title compound, [Sn2Cl2(CH3)4(C6H5N2O2)2], forms infinite one-dimensional zigzag chains that propagate in a helical fashion along the c axis via an Sn—O=C—O—Sn—O bridge which involves the carboxyl­ate groups of two methyl­pyrazine­carboxyl­ate ligands. These display both chelating and bridging coordination behaviour. The asymmetric unit contains two Sn atoms; one adopts a distorted trigonal–bipyramidal geometry, while the other is in a distorted penta­gonal–bipyramidal configuration. [ABSTRACT FROM AUTHOR]
