Аннотация: The reaction of [Cp(CO)(2)Re-C-CHPh] (1) with [Pd(PPh3)(4)] followed by the treatment of resulting [Cp(CO)(2)RePd(mu-C=CHPh)(PPh3)(2)] (2) with diphosphines (dppe, dppp) gave new complexes [Cp(CO)(2)RePd(mu-C=CHPh)(dppe)] (3) and [Cp(CO)(2)RePd(mu-C=CHPh)(dppp)] (4). Treatment of the synthesized complexes with [Fe-2(CO)(9)] led to mixtures of [Cp(CO)(2)ReFe(mu-C=CHPh)(CO)(4)] (5), [(dppe) PdFe2(CO)(8)] (6), [CpReFe2(mu(3)-C=CHPh)(CO)(8)] (7), [CpReFePd(mu(3)-C=CHPh)(CO)(5)(dppe)] (8) and of 5, [(dppp)PdFe2(CO)(8)] (9), [CpReFePd(mu(3)-C=CHPh)(CO)(5)(dppp)] (10), respectively. The main products of both reactions were trinuclear mu(3)-vinylidene clusters 8 and 10. Reactions of the trinuclear mu(3)-vinylidene ReFePd clusters 8 and 10 with Fe-2(CO)(9) were also studied. New complexes were characterized by IR, H-1, C-13, P-31 NMR spectroscopy and cyclic voltammetry. The structure of [CpReFe2(mu(3)-C=CHPh)(CO)(8)] was determined by single-crystal X-ray diffraction.
