Abstract

A new cobalt complex [Co(dppaPh)2(CH3CN)2](BF4)2 (1) (dppaPh = N,N-bis(diphenylphosphino)aniline) is synthesized and structurally characterized. The structural features of this complex are compared with those of previously described complex [Co(dppaPh)2(η1-P4)]BF4 whose coordination sphere contains an η1-coordinated molecule of white phosphorus. The role of the solvent in the crystallization of 1 is established: the reaction in CH3CN yields a stable octahedral complex with two solvent molecules coordinated in axial positions.
