Ultraviolet irradiation of [Fe(p-xylene)(Cp)]- [PF6] and tris(diphenylphosphino)methane (tppm) gives [Fe{HC(PPh2)3}(Cp)] [PF6] in 96% yield. Crystal structure analysis (R = 6.2%) shows that all three phosphorus atoms are coordinated to the Iron atom, providing the first example of η3 coordination of tppm on a single metal. There is considerable strain in the tricyclic system, with all three P-C-P angles less than 90°. One Fe-P bond is easily opened by refluxing acetonitrile, giving [Fe-(MeCN)η2-tppm)(Cp)][PF6].
