Abstract
The reaction of CuCl, LiAs(SiMe3)2 and dppb (Bis(diphenylphosphino)butane) leads to the formation of ionic cluster complexes. Depending on the reaction conditions one can isolate [Cu8As3(AsSiMe3)2(dppb)4]+[Cu{As2(SiMe3)2}{As4(SiMe3)4}]- (1) and [Cu8As3(AsSiMe3)2(dppb)4]+[Cu{As(SiMe3)2}2]- (2). The same reaction of CuCl, dppm (Bis(diphenylphosphino)methane) and LiSb(SiMe3)2 leads to the neutral cluster complex [Cu10(Sb3)2(SbSiMe3)2(dppm)6] (3). The structures of 1-3 have been solved by X-ray single crystal analyses.
