cis-Bis(2,2′-bipyridine-κ2N,N′)bis(dimethyl sulfoxide-κO)zinc bis(tetraphenylborate) dimethyl sulfoxide monosolvate

Abstract

In the mononuclear title complex, [Zn(C10H8N2)2(C2H6OS)2](C24H20B)2·C2H6OS, the ZnII ion is coordinated by four N atoms of two bidentate 2,2′-bipyridine molecules and by the O atoms of two cis-disposed dimethyl sulfoxide molecules in a distorted octahedral geometry. The S atom and the methyl groups of one of the coordinated dimethyl sulfoxide molecules are disordered in a 0.509 (2):0.491 (2) ratio. The crystal packing is stabilized by C—H...O hydrogen bonds between the dimethyl sulfoxide solvent molecules and tetraphenylborate anions.
