Abstract

The new bridging methylene complex (CO)₄FePt (PPh₃)₂(μ-CH₂), has been prepared by the reaction of Fe₂(μ-CH₂)(CO)₈ with Pt(PPh₃)₂(CH₂CH₂) and has been crystallographically characterized: P2₁/c, a = 10.338(2), b = 19.604(5), c = 18.422(4) Å, β = 105.30(2), D_c = 1.65, Z = 4, R = 3.54, R_w = 3.64 for 4052 reflections with F_o ≥ 5 σ(F_o). The iron atom has a distorted octahedral geometry defined by the four carbonyl ligands, the platinum atom, and the methylene ligand, whereas the platinum center has a distorted square planar geometry.
