| 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. |
