Reaction of [Ir(cod)(µ-pz)]2(cod = cyclo-octa-1,5-diene; pzH = pyrazole)with Ph2PH results in hydrogenation of cod at one Ir centre to give a 1-Ï ,4-5-η-C8H13(i.e. -enyl) unit, affording the complex [Ir(cod)(µ-pz)(µ-PPh2)2Ir(C8H13)] in which Irâ Ir = 2.780 à and both pz and PPh2ligands occupy unsymmetrical bridging positions.
