Abstract
The single crystal X-ray diffraction study of the heterometallic cluster CpMnFePt(m3-C=CHPh)(PPh3)(CO)6 is performed. The crystallographic characteristics are as follows: a = 32.356(15) Å, b = 11.754(5) Å, c = 20.114(9) Å, β = 115.707(6)°, V = 6893(5) Å3, space group C2/c, Z = 8, dcalc = 1.741 g/cm3. The cluster molecule contains a bridging phenylvinylidene ligand coordinated to a metallic core in the form of a Mn-Fe-Pt chain (the Mn-Fe and Fe-Pt bond lengths are 2.6768(14) Å and 2.6280(11) Å respectively and the Mn⋯Pt distance is 3.6425(19) Å).
