摘要：

Treatment of Au2(Ph2PCH2CH2PPh2)Cl2 with one equivalent of the [Ru5C(CO)14]2- dianion in the presence of TlPF6 gives Ru5C(CO)14Au2(Ph2PCH2CH2PPh2) (1) in good yield and the [(Ru5C(CO)14}2Au2(Ph2PCH2CH2PPh2)]2- (2) anion in low yield. Complex 2 becomes the major product if 2 equivalents of [Ru5C(CO)14]2- are used. Reaction of [Au2(Ph2PCH2 CH2PPh2)Cl2] with 3 equivalents of [H3Os4(CO)12]- anion in the presence of TlPF6 affords (H3Os4(CO)12)2Au2(Ph2PCH2CH2PPh2) (3) in reasonable yield. X-ray diffraction studies of 1 and 3 show that they contain the [Au2(Ph2PCH2CH2PPh2)]2+ fragment in different coordination modes.
