Inspired by the monodentate P, N ligation strategy featured in Crabtree's catalyst [(COD)Ir(PCy3)(Py)](+) PF6- ([1](+) PF6-), a new class of bidentate cationic ([2]+ X-) and zwitterionic ( 3) Ir complexes have been developed, which are capable of mediating the hydrogenation of alkenes under mild conditions and in a wider range of solvents than is possible for [1]+ PF6-.
