Abstract The interaction between Cp(CO) 2 RePt(μ-C CHPh)(PPh 3 ) 2 ( 1 ) and Fe 2 (CO) 9 afforded the new heterometallic μ 3 -vinylidene cluster CpReFePt(μ 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) A; the Re⋯Pt distance is 3.3523(7) A; the bond angle Re–Fe–Pt is 76.55(3)°. The μ 3 -C CHPh ligand is η 1 -bound to the Re and Pt atoms and η 2 -coordinated to the Fe atom. The C C bond length is 1.412(4) A. 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.
