ABSTRACT
The title zinc complex, [ZnCl2(C18H22N4)], contains a bidentate 1,2-bis(3,5-dimethyl-1H-pyrazol-1-ylmethyl)benzene ligand that binds to the zinc atom, forming a nine-membered metallocyclic ring. The geometry about the Zn atom is distorted tetrahedral, with the largest deviation observed in the magnitude of the Cl—Zn—Cl angle. Similar distortions are observed in the cobalt analogue and related zinc compounds containing metallocyclic rings with more than six members. The copper analogue exhibits a more severe distortion of the metal coordination sphere than is observed in the title compound.
