Iridium nitrosyl complexes of 9,10-phenanthrenequinone di-imine. Crystal structure of [Ir(NO){HNC14H8N(PPh3)}(PPh3)][PF6], a species containing a phosphazene–imido-ligand

Abstract

9,10-Phenanthrenequinone di-imine (H2pqd) reacts with [Ir(NO)(MeCN)3(PPh3)2]2+ yielding the expected five-co-ordinate [Ir(NO)(H2pqd)(PPh3)2]2+ which, by treatment with weak bases, gives the monocationic title compound, whose structure has been determined crystallographically. The compound is monoclinic, space group P21, with a= 10.867(4), b= 22.423(8), c= 9.227(4)Å, β= 101.12(4)°, and Z= 2. It contains a phosphazene–Imido-ligand, formed by transfer of a triphenylphosphine group from the metal to an imino-nitrogen atom, a nitrosyl group, and a triphenylphosphine molecule, in a nearly square-planar arrangement.
