respectively. The activations are sequential, with the second generally being the slowest. Accordingly, dihydride intermediates IrH2κ2-C,N-[C6H4-isoqui-O-C6H5]}(PiPr3)2 (2d), IrH2κ2-N,N-[NBzim-py-C6H5]}(PiPr3)2 (3d), IrH2κ2-N,N-[Ind-py-C6H5]}(PiPr3)2 (4d), and IrH2κ2-N,C-[py-C6HMe2-py]}(PiPr3)2 (7d) were characterized spectroscopically. Complexes 3 and 5 are green phosphorescent emitters upon photoexcitation
