Phosphine complex nonelectrolytes with

These complexes are isoelectronic and isostructural with the bis-phosphine Ir carbonyl chloride complex, but they differ in two respects (a) the reaction with is irreversible and (b) the oxidative addition of yields three different cis isomers as a result of a solvent dependence for this addition. The complexes trans-CPR ROjIrCCOftr-carb) (R = CjHj R = CgHj, CHj) react with or D, giving the (PR ROjIrH (or D ) (CO)((T-carb) dihydrides or dideuterides. These complexes are colorless crystalline compounds, nonelectrolytes in solution and stable with respect to thermal loss of either carborane or H, however, they are light sensitive.
