Crystal structure of (μ 2 -7-{[bis(pyridin-2-ylmethyl)amino-1κ 3 N , N ′, N ′′]methyl}-5-chloroquinolin-8-olato-2κ N ;1:2κ 2 O )trichlorido-1κ Cl ,2κ 2 Cl -dizinc(II)

The title compound, [Zn 2 (C 22 H 18 ClN 4 O)Cl 3 ], is a dinuclear zinc(II) complex with three chlorido ligands and one pentadentate ligand containing quinolin-8-olato and bis(pyridin-2-ylmethyl)amine groups. One of the two Zn II atom adopts a tetrahedral geometry and coordinates two chlorido ligands with chelate coordination of the N and O atoms of the quinolin-8-olato group in the ligand. The other Zn II 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-ylmethyl)amine unit. In the crystal, two molecules are associated through a pair of intermolecular C—H...Cl hydrogen bonds, forming a dimer with an R 2 2 (12) ring motif. Another intermolecular C—H...Cl hydrogen bond forms a spiral C (8) chain running parallel to the [010] direction. The dimers are linked by these two intermolecular C—H...Cl hydrogen bonds, generating a ribbon sheet structure in ac plane. Two other intermolecular C—H...Cl hydrogen bonds form a C (7) chain along the c -axis direction and another C (7) chain generated by a d -glide plane. The molecules are cross-linked through the four intermolecular C—H...Cl hydrogen bonds to form a three-dimensional network.
