Bis(triphenylphosphine)iron tricarbonyl is a coordination complex with the formula Fe(CO)₃(PPh₃)₂ (Ph = C₆H₅). A yellow solid, the complex is derived from iron pentacarbonyl by replacement of two carbonyl ligands by triphenylphosphine (PPh₃). It can be produced by borohydride-catalyzed substitution of the pentacarbonyl.[1] Protonation gives the ferrous hydride.[2] The complex adopts trigonal bipyramidal structure with trans phosphines. (Triphenylphosphine)iron tetracarbonyl is an intermediate in the synthesis of this compound. Both the mono- and bis(triphenylphosphine) complexes were originally describe by Walter Reppe.[3]
