Dichlorido{N-[1-(2-pyridyl)ethylidene]ethane-1,2-diamine}copper(II)

Abstract

The title complex, [CuCl2(C9H13N3)], is mononuclear and contains a five-coordinate CuII atom. The geometry of the CuII atom can be described as tetragonal-pyramidal derived from the calculation of the value τ = 0.102. The three N atoms of the pyridine and ethane-1,2-diamine ligands and one Cl atom belong to the basal plane and the other Cl atom represents the axial position of the pyramid. The Cu atom is displaced by 0.2599 (2) Å from the basal plane towards the axial Cl atom. In the crystal, molecules are linked into chains by intermolecular N—H...Cl and C—H...Cl hydrogen bonds.
