Bis(2-{[2-(isopropylazaniumyl)ethyl]iminomethyl}-6-methoxyphenolato)copper(II) bis(thiocyanate)

Abstract

The asymmetric unit of the title compound, [Cu(C13H20N2O2)2](NCS)2, contains one half-dication, located on an inversion center, and one thiocyanate anion. Each CuII atom is four-coordinated by two phenolate O and two imine N atoms from two symmetry-related Schiff base 2-{[2-(isopropylazaniumyl)ethyl]iminomethyl}-6-methoxyphenolate (L) ligands in a distorted square-planar geometry. The ammonium groups are involved in the formation of N—H...O and N—H...N hydrogen bonds, which link one dication and two anions into an electroneutral cluster. When very weak Cu—N interactions with a distance of 2.910 (5) Å between the metal and the thiocyanate anions in apical positions are considered, the secondary coordination polyhedron is a very elongated CuN4O2 octahedron.
