Bis(2,2′-bi-1H-imidazole-κ2N3,N3′)bis(dimethyl sulfoxide-κO)copper(II) bis(tetrafluoridoborate)

Abstract

In the title copper(II) salt, [Cu(C6H6N4)2(C2H6OS)2](BF4)2, the Jahn–Teller distorted octahedral coordination sphere of copper is formed from four 2,2′-bi-1H-imidazole N atoms and two dimethyl sulfoxide O atoms. The Cu atom lies on a center of inversion. N—H...O and N—H...F hydrogen bonds give rise to a one-dimensional structure. The BF4− anion is disordered over two sites in a 0.671 (10):0.329 (10) ratio.
