title: Bis(2-{[2-(isopropyl-aza-nium-yl)eth-yl]imino-meth-yl}-6-meth-oxy-phenolato)copper(II) bis-(thio-cyanate).
abstract: The asymmetric unit of the title compound, [Cu(C(13)H(20)N(2)O(2))(2)](NCS)(2), contains one half-dication, located on an inversion center, and one thio-cyanate 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-(isopropyl-aza-nium-yl)eth-yl]imino-meth-yl}-6-meth-oxy-phenolate (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 CuN(4)O(2) octahedron.
