The dinuclear title complex, [Sn(2)(C(7)H(6)Cl)(4)(C(9)H(16)NO(2)S(2))(4)], lies on a center of inversion. The Sn(IV) atoms are chelated by one of the two carboxyl-ate ions; the other carboxyl-ate ion bridges two metal atoms. The geometry of the six-coordinate Sn(IV) atom is a distorted trans-C(2)SnO(4) octa-hedron [C-Sn-C = 155.32 (8)°].

The title compound, [Zn(CHClNO)Cl], is a dinuclear zinc(II) complex with three chlorido ligands and one penta-dentate ligand containing quinolin-8-olato and bis-(pyridin-2-ylmeth-yl)amine groups. One of the two Zn atom adopts a tetra-hedral geometry and coordinates two chlorido ligands with chelate coord-ination of the N and O atoms of the quinolin-8-olato group in the ligand. The other Zn atom adopts a distorted trigonal-bipyramidal geometry, and coordinates one chlorido-O atom of the quinolin-8-olato group and three N atoms of the bis-(pyridin-2-ylmeth-yl)amine unit.

Reaction of copper(I)chloride with 2,3-di-methyl-pyrazine in ethanol leads to the formation of the title compound, poly[[μ-chlorido-μ-(2,3-di-methyl-pyrazine)-copper(I)] ethanol hemisolvate], {[CuCl(CHN)]·0.5CHOH} or CuCl(2,3-di-methyl-pyrazine) ethanol hemisolvate. Its asymmetric unit consists of two crystallographically independent copper cations, two chloride anions and two 2,3-di-methyl-pyrazine ligands as well as one ethanol solvate mol-ecule in general positions.

Crystallization of 5-nona-noyl-8-hy-droxy-quinoline in the presence of InCl in aceto-nitrile yields a dinuclear In complex crystallizing in the space group . In this complex, [In(CHNO)Cl(HO)], each indium ion is sixfold coordinated by two chloride ions, one water mol-ecule and two 8-quinolino-late ions. The crystal of the title complex is composed of two-dimensional supra-molecular aggregates, resulting from the linkage of the O-H⋯O=C and O-H⋯Cl hydrogen bonds as well as bifurcated C-H⋯Cl contacts.

The title compound, [Zn(CHO)(CHN)]·3HO or {Zn[(CHN)NH][μ-(CH)(COO)]}·3HO, was separ-ated from the solvothermal reaction of zinc(II) sulfate hepta-hydrate, 2,2'-di-pyridyl-amine and sodium adipate. The dinuclear metal complex has a centrosymmetric structure, with the Zn atom adopting a highly distorted octa-hedral coordination sphere composed of four oxygen atoms from bridging adipato ligands and two pyridine nitro-gen atoms. In the crystal, the title compound aggregates into a tri-periodic supra-molecular structure through inter-molecular hydrogen-bonding networks of the form O-H⋯O and N-H⋯O.

The title compound, bis-[μ-2,2'-(4-1,2,4-triazole-3,5-di-yl)di-acetato]-bis-[di-aqua-copper(II)] dihydrate, [Cu(CHNO)(HO)]·2HO, is a dinuclear octa-hedral Cu triazole-based complex. The central copper atoms are hexa-coordinated by two nitro-gen atoms in the equatorial positions, two equatorial oxygen atoms of two carboxyl-ate substituents in position 3 and 5 of the 1,2,4-triazole ring, and two axial oxygen atoms of two water mol-ecules. Two additional solvent water mol-ecules are linked to the title mol-ecule by O-H⋯N and O⋯H-O hydrogen bonds.
