Abstract
Reaction of tert -butyl isocyanide with [Ir(COD)Cl] 2 and NH 4 PF 6 yields [Ir(CNBu t ) 5 H](PF 6 ) 2 ( 1 ). The hydride ligand is observed by both proton NMR and infrared spectroscopy. Complex 1 is triclinic, P-1, a = 11.307(3), b = 14.619(3), c = 15.486(3) Å, f = 98.204(3), g = 106.851(3), n = 106.953(3)°, Z = 2, 6746 reflections [I S 2 σ (I)], R1 = 0.0397, w R 2 = 0.0984. The closest Ir-Ir interatomic distance within the crystal is 8.6 Å. EPR and cyclic voltammetry studies also support the identity of 1 .
