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

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 Cu-II 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 center dot center dot center dot O and N-H center dot center dot center dot 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) angstrom between the metal and the thiocyanate anions in apical positions are considered, the secondary coordination polyhedron is a very elongated CuN4O2 octahedron.
