Аннотация: A series of trinuclear mu(3)-vinylidene ReFePt clusters were synthesized by the application of two approaches: (i) reactions of the binuclear RePt mu-vinylidene complexes with Fe-2(CO)(9); (ii) ligand substitution or exchange reactions at the Pt atom in the synthesized ReFePt clusters. The molecular structures of CpReFePt(mu(3)-C=CПоказать полностьюHPh)(CO)(5)[P(OEt)(3)]L [L = CO; P(OEt)(3)] were determined by an X-ray diffraction study. The obtained compounds were studied by IR and H-1, C-13 and P-31 NMR spectroscopy. The spectroscopic study revealed that the clusters CpReFePt(mu(3)-C=CHPh)(CO)(5))[P(OEt)(3)]L [L = CO; P(OEt)(3)] and CpReFePt(mu(3)-C=CHPh)(CO)(6)[P(OPri)(3)] undergo isomerization upon dissolution, resulting in three isomers with different positions of the mu(3)-vinylidene ligand over the ReFePt core. The redox properties of the clusters were studied by electrochemical methods. The relatively stable cation-radicals obtained by chemical oxidation of CpReFePt(mu(3)-C=CHPh)(CO)(6)[P(OPri)(3)] and CpReFePt(mu(3)-C=CHPh)(CO)(5)[P(OEt)(3)](2) with ferrocenium tetrafluoroborate were characterized by EPR spectroscopy.
