Crystal structure of (μ2-7-{[bis­(pyridin-2-ylmeth­yl)amino-1κ3N,N′,N′′]meth­yl}-5-chloro­quinolin-8-olato-2κN;1:2κ2O)tri­chlorido-1κCl,2κ2Cl-dizinc(II)

Abstract

The title compound is a dinuclear zinc(II) complex with three chlorido ligands and one penta­dentate ligand containing quinolin-8-olato and bis­(pyridin-2-ylmeth­yl)amine units. One Zn^II atom has a tetra­hedral coordination environment by two chlorido and chelate coordination of the N and O atoms of the quinolin-8-olato unit in the penta­dentate ligand, and the other has a distorted trigonal–bipyramidal coordination environment by one chlorido and four donating atoms except for the N atom of the quinolin-8-olato in the penta­dentate ligand. In the crystal, the mol­ecules are linked by four different kinds of inter­molecular C—H⋯Cl hydrogen bonds, forming a three-dimensional network structure.

The title compound, [Zn₂(C₂₂H₁₈ClN₄O)Cl₃], 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 R₂²(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.
