Abstract

The title compound, [FePt(C12H10P)(C13H13Si)(C18H15P)2(CO)3]·0.5CH2Cl2, represents an example of a phosphido-bridged heterobimetallic silyl complex; these are inter-esting precursors for the coordination and activation of small unsaturated organic mol-ecules. The μ2-PPh2 ligand spans the iron and platinum atoms, which are connected via a metal-metal bond of 2.7738 (4) Å. In contrast to most other complexes of the [(OC)3Fe(SiR 3)(μ-PR 2)PtL 2] family, where the iron-bound SiR 3 group is trans-arranged with respect to the μ2-PPh2 ligand, the SiPh2Me ligand is roughly collinear with the Fe-Pt vector [Si-Fe-Pt = 169.07 (3)°].
