Abstract
The X-ray diffraction study of a new heterometallic cluster CpReFePt(μ3-C=CHPh)(CO)5[P(OPri)3]2 is performed. The crystallographic characteristics are as follows: a = 11.0275(4) Å, b = 33.0367(12) Å, c = 12.2691(5) Å, β = 98.3660(10)°, V = 4422.2(3) Å3, space group P21/n , Z = 4, dcalc = 1.744 g/cm3. The cluster contains the phenylvinylidene ligand coordinated with a trimetallic core in the form of a Re-Fe-Pt chain (the Re-Fe and Fe-Pt bond lengths are 2.794(7) Å and 2.628(1) Å respectively; the Re∙∙∙Pt distance is 3.354(1) Å).
