Crystal structure of dichloridobis[2-(phenyldiazenyl)pyridine-κN1]zinc

Abstract

The structure of the title complex, [ZnCl2(C11H9N3)2], comprises two 2-(phenyldiazenyl)pyridine ligands coordinating to a central ZnII dichloride unit via the pyridyl N-atom donors, resulting in a slightly distorted tetrahedral geometry. The complex exhibits twofold rotation symmetry, with the rotation axis bisecting the zinc cation. The structure is stabilized by weak intermolecular C—H...Cl interactions [C...Cl = 3.411 (2) and 3.675 (2) Å], connecting neighbouring molecules into layers perpendicular to the c axis.
