The preparation and crystal structure of µ-oxido-bis[triphenylphosphinenitrosyliridium(I)]: a novel iridium nitrosyl compound containing a bridging oxygen and a bent metal–metal bond
Abstract
µ-Oxido-bis[triphenylphosphinenitrosyliridium(I)]–C6H6 has been prepared by the reaction of trans-Ir(CO)Cl(PPh3)2 and nitrite ion in benzene–aqueous alcohol: its structure contains the first example of a bent iridium–iridium bond and a nitrosyl group π-bonded to an iridium atom.
