The complexation of the mixed bidentate ligands 1-diphenylphosphino-1′-diphenylthiophosphinoferrocenyl and 1,2-bis-(diphenylphosphino)ferrocenyl with rhodium(I) and palladium(II) species yield a range of mono- and dirhodium or palladium complexes. Their interest as possible catalysts for alkene hydroformylation and alkoxycarbonylation and Heck coupling reactions has been assessed. Fe[C₅Me₄P(S)Ph₂][C₅Me ₄PPh₂]PdCl₂ and Fe[C₅H₂-1,2-(PPh₂)₂-4- ^tBu][C₅H₅]PdCl₂ have been characterized by single-crystal X-ray diffraction studies.
