Crystal structure of {N-[(6-bromopyridin-2-yl)(phenyl)methylidene]-2,6-dimethylaniline-κ2N,N′}dichloridozinc dichloromethane hemisolvate

Abstract

The solvated title compound, [ZnCl2(C20H17BrN2)]·0.5CH2Cl2, comprises a bidentate iminopyridine ligand and two Cl atoms bound to a zinc2+cation in a distorted tetrahedral arrangement. The chelate bond lengths are consistent with localized C=N double bonds and a C—C single bond, as expected for an unreduced ligand bound to a closed-shell transition metal cation. Apart from weak nonclassical C—H...Cl hydrogen bonds between the complex molecules and the disordered solvent molecules (occupancy = 0.5), no further significant intermolecular interactions are observed.
