Crystal structure of (μ(2)-7-{[bis-(pyridin-2-ylmeth-yl)amino-1κ(3) N,N',N'']meth-yl}-5-chloro-quinolin-8-olato-2κN;1:2κ(2) O)tri-chlorido-1κCl,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 penta-dentate ligand containing quinolin-8-olato and bis-(pyridin-2-ylmeth-yl)amine groups. One of the two Zn(II) atom adopts a tetra-hedral geometry and coordinates two chlorido ligands with chelate coord-ination 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-ylmeth-yl)amine unit. In the crystal, two mol-ecules are associated through a pair of inter-molecular C-H⋯Cl hydrogen bonds, forming a dimer with an R (2) (2)(12) ring motif. Another inter-molecular C-H⋯Cl hydrogen bond forms a spiral C(8) chain running parallel to the [010] direction. The dimers are linked by these two inter-molecular C-H⋯Cl hydrogen bonds, generating a ribbon sheet structure in ac plane. Two other inter-molecular 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 mol-ecules are cross-linked through the four inter-molecular C-H⋯Cl hydrogen bonds to form a three-dimensional network.
