摘要
Reaction of M-3(CO)(12-n)(Ph(2)Ppy)n (M = Ru, n = 3; M = Os, n = 1) with HgX2 O( = Br, Cl) gave cis-M(CO)(3)(mu-Ph(2)Ppy)(HgX)(2), (M=Ru, 1; M=Os, 2), and the reaction of Ru-3(CO)(9)(Ph(2)Ppy)(3) with CdI2 resulted in the formation of I(CO)(2)Ru(mu- Ph(2)Ppy)(2)Ru(CO)(2)I, 3, which demonstrate the cleavage of metal-metal bonds by Lewis acids. The crystal and molecular structures of 1, 2 and 3 .0.5MeOH . H2O have been determined by X-ray analysis. (C) 1998 Elsevier Science S.A. All rights reserved.
