The title compound, [FePt(C(9)H(9)NO(2)S)(C(18)H(15)P)(C(25)H(22)P(2))(CO)(3)], represents a rare example of an isonitrile-bridged heterobimetallic complex (here Pt and Fe) and is an inter-esting precursor for the preparation of heterodinuclear μ-amino-carbyne complexes, since the basic imine-type N atom of the μ(2)-C=N-R ligand readily undergoes addition with various electrophiles to afford iminium-like salts. In the crystal, the almost symmetrically bridging μ(2)-C=N-R ligand (neglecting the different atomic radii of Fe and Pt) is strongly bent towards the Fe(CO)(3) fragment, with a C=N-R angle of only 121.1 (4)°.
