Synthesis and crystal structure of bis-[μ2-7-({bis-[(pyridin-2-yl)meth-yl]amino-κ3 N,N',N''}meth-yl)-5-chloro-quinolin-8-olato-κ2 N,O]dizinc(II) bis-(perchlorate) aceto-nitrile monosolvate.

The title compound, [Zn2(C22H18ClN4O)2](ClO4)2·CH3CN, consists of one centrosymmetric cationic dinuclear zinc(II) complex with two penta-dentate ligands containing quinolin-8-olato and bis-(pyridin-2-ylmeth-yl)amine groups, two perchlorate counter-ions and one aceto-nitrile solvate mol-ecule. The ZnII atom adopts a distorted octa-hedral geometry and coordinates the O atom and the N atom of the quinolin-8-olato group and three N atoms of the bis-(pyridin-2-ylmeth-yl)amine group in a ligand, and the O atom in an adjacent ligand generated by an inversion operation. The phenolato oxygen atoms in the two ligands of the cationic dinuclear complex are bridging coordinated with the two ZnII atoms. In the crystal, the cationic dinuclear complex mol-ecules and perchlorate ions are linked by C-H⋯Cl and C-H⋯O hydrogen bonds, forming a three-dimensional network.
