Two isomeric series (α and β) of hydrido complexes of iridium with methyldiphenyl arsine of the general formula IrHX 2 (Ph 2 AsMe) 3 (X = Cl, Br or I) have been prepared and characterised. The α compounds are prepared by reacting the metal halide and the arsine in alcoholic medium with zinc and the corresponding halogen acid, while the β compounds are prepared by refluxing the metal halide and the arsine in alcoholic medium in presence of potassium hydroxide. The properties of these hydrido complexes are compared with the corresponding trihalogeno complexes of the general formula IrX 3 (Ph 2 AsMe) 3 . Hydrides of rhodium of the general formula RhHX 2 (Ph 2 AsMe) 3 , prepared earlier using hypophosphorous acid as reducing agent, can be made by other methods.
