Аннотация: The interaction between Cp(CO)(2)RePt(mu-C=CHPh)(PPh(3))(2) (1) and Fe(2)(CO)(9) afforded the new heterometallic mu(3)-vinylidene cluster CpReFePt(mu(3)-C=CHPh)(CO)(6)(PPh(3)) (2). An X-ray diffraction study shows the complex 2 possesses a trimetallic Re-Fe-Pt chain core. The bond lengths are Re-Fe 2.8221(8), Fe-Pt 2.5813(8) angstrom; the Re center dot center dot center dot Pt distance is 3.3523(7) angstrom; the bond angle Re-Fe-Pt is 76.55(3)degrees. The mu(3)-C=CHPh ligand is eta(1)-bound to the Re and Pt atoms and eta(2)-coordinated to the Fe atom. The C=C bond length is 1.412(4) angstrom. The Pt atom is coordinated by the PPh(3) and CO groups. Complex 2 is characterized by the IR and (1)H, (13)C and (31)P NMR spectra. (C) 2008 Elsevier B.V. All rights reserved.
