چکیده
In the centrosymmetric title compound, [Zn(4)(C(9)H(6)NO)(6)(C(2)H(3)O(2))(2)]·2H(2)O, the Zn(II) atom that is bonded to one O atom of the acetate group is chelated by a quinolin-8-olate anion. This Zn atom is also bonded to the oxide O atoms of two other quinolin-8-olate anions, which themselves engage in chelation to the other Zn(II) atoms. The Zn(II) atom is five-coordinate in a square-pyramidal coordination geometry. The second Zn(II) atom is six-coordinate as it is linked to two oxide O atoms of the anions that chelate to the acetate-bound metal atom, and is chelated by two quinolin-8-olate ligands. The uncoordinated water mol-ecule is disordered over two positions in a 4:1 ratio. O-H⋯O hydrogen bonds between the water molecules and the free O atoms of the carboxylate groups consolidate the crystal packing.

Both independent Pb(II) atoms in the title compound, [Pb(2)(C(10)H(8)NO)(2)(C(2)H(3)O(2))(2)], are chelated by acetate and substituted quinolin-8-olate anions; the O atoms of the quinolin-8-olates also bridge to confer a five-coordinate status to each metal center. The geometry approximates a distorted Ψ-fac octa-hedron in which one of the sites is occupied by a stereochemically active lone pair.

The mol-ecule of the title compound, [Pb(2)(C(10)H(8)NO)(2)(NO(3))(2)(CH(3)OH)(2)], lies about a centre of inversion. The Pb atom is chelated by nitrate and substituted quinolin-8-olate anions. The O atom of the quinolin-8-olate also bridges, to confer a six-coordinate status on the metal centre. When a longer Pb⋯O inter-action is considered, the geometry approximates a Ψ-cube in which one of t...

The Sn(IV) atom in the centrosymmetric dinculear title compound, [Sn(2)(CH(3))(2)(C(6)H(5))(2)(C(9)H(6)NO)(2)Cl(2)], shows a trans-C(2)SnNO(2)Cl distorted octa-hedral coordination [C-Sn-C = 157.83 (8)°]. The quinolin-8-olate anion chelates to the Sn atom; its O atom also binds to the inversion-related Sn atom, forming the dinuclear compound. In the crystal structure, weak inter-molecular C-H⋯Cl...

The reaction of zinc acetate and 2-methyl-8-hydroxy-quinoline in methanol yielded the centrosymmetric dinuclear title compound, [Zn(2)(C(10)H(8)NO)(2)(CH(3)CO(2))(2)(CH(3)OH)(2)], which has the Zn atom within a distorted NO(4) trigonal-bipyramidal coordination geometry. Methanol-acetate O-H⋯O hydrogen bonds link the dinculear units into a linear supra-molecular chain extending parallel to [100].
