title: Bis(2,2'-bi-1H-imidazole-κN,N)bis-(dimethyl sulfoxide-κO)copper(II) bis-(tetra-fluoridoborate).
abstract: In the title copper(II) salt, [Cu(C(6)H(6)N(4))(2)(C(2)H(6)OS)(2)](BF(4))(2), the Jahn-Teller distorted octa-hedral 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 BF(4) (-) anion is disordered over two sites in a 0.671 (10):0.329 (10) ratio.
