چکیده
The dinuclear title compound, [Pb(2)(C(10)H(6)NO(2))(2)(CH(3)COO)(2)(CH(3)OH)(2)], lies across an inversion center. The methanol-coordinated Pb(II) atom is chelated by the acetate anion as well as by the quinoline-2-carboxyl-ate anion. One O atom of the quinoline-2-carboxyl-ate anion bridges two symmetry-related Pb(II) atoms, forming the dinuclear compound. Aside from the six atoms connected to the Pb(II) atom by regular coordination bonds, the structure features a long Pb⋯O inter-action [3.145 (3) Å] that gives rise to a distorted Ψ-square-anti-prismatic geometry at the metal center. The H atom of the methanol is hydrogen bonded to an O atom of the acetate.

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].

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 neutral binuclear title complex, [Cd(2)(C(16)H(10)NO(2))(4)(C(10)H(8)N(2))(2)], is centrosymmetric, with the inversion center generating the central (μ-O)(2)Cd(2) bridge. The Cd(II) ion is in a strongly distorted CdN(2)O(5) penta-gonal-bipyramidal geometry, defined by two N atoms from one 2,2'-bipyridine ligand and five O atoms from three 2-phenyl-quinoline-4-carboxyl-ate ligands, one monod...

In the centrosymmetric dinuclear title compound, [Pb(2)(C(10)H(6)NO(2))(2)(CH(3)COO)(2)(C(2)H(5)OH)(2)], one O atom of the carboxyl-ate group of the quinoline-2-carboxyl-ate anion connects the two Pb(II) atoms. The Pb(II) atom is surrounded by four O atoms and one N atom in a Ψ-octa-hedral PbO(4)NE geometry (E is the electron lone pair). Two longer Pb⋯O inter-actions distort the geometry toward...

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.
