Molecular tripods synthesis

Of the molecular hydrogen complexes that were first synthesized, none were the d ML4(H2) type. This is not at all surprising because it is well known that d ML4 systems yield oxidative addition with formation of a dihydride. Application by Bianchini et al of the novel tripodal phosphine ligand to the rhodium atom led to the synthesis of the first compound in this class, the [Rh(P(CH2CH2PPh2)3(H2)] complex [24].
