In the mononuclear title complex, [Zn(C 10 H 8 N 2 ) 2 (C 2 H 6 OS) 2 ]- (C 24 H 20 B) 2 C 2 H 6 OS, the Zn II ion is coordinated by four N atoms of two bidentate 2,2 0 -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—HO hydrogen bonds between the dimethyl sulfoxide solvent molecules and tetraphenyl- borate anions.
