Bis(μ-2-methyl-quinolin-8-olato)-κN,O:O;κO:N,O-bis-[(acetato-κO)(methanol-κO)zinc(II)].

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].

8-Hydr-oxy-2-methyl-quinolinium dichlorido(2-methyl-quinolin-8-olato-κN,O)zincate(II) methanol solvate.

The reaction of zinc chloride and 2-methyl-8-hydroxy-quinoline in methanol yielded the title monosolvated salt, (C(10)H(10)NO)[ZnCl(2)(C(10)H(8)NO)]·CH(3)OH, which has the Zn atom within a distorted Cl(2)NO tetra-hedral coordination geometry. Supra-molecular chains feature in the crystal structure, comprising all components of the structure stabilized by a combination of O-H⋯O, N-H⋯O and O-H⋯Cl hydrogen bonding.

Bis(acetato-κO)bis-(μ(3)-quinolin-8-olato-κN,O:O:O)tetra-kis(μ(2)-quinolin-8-olato-κN,O:O)tetra-zinc(II) dihydrate.

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.
