Hydrido(prolinato-κ 2 N , O )tris(trimethylphosphane-κ P )iridium(III) hexafluoridophosphate

The title complex, [Ir(C 5 H 8 NO 2 )H(C 3 H 9 P) 3 ]PF 6 , has two independent anion–cation pairs in the asymmetric unit. The geometry about each Ir III atom is pseudo-octahedral with a meridional arrangement of the P(CH 3 ) 3 ligands, N , O -bidentate coordination of prolinate and a hydride ligand trans to the prolinate N atom. The independent Ir III moieties are joined by N—H...O hydrogen bonds and the N—H...O bonding motif continues throughout the structure, creating an extended chain parallel to the c- axis direction. The methyl groups of one P(CH 3 ) 3 ligand are rotationally disordered over two sets of sites in a 0.62 (2):0.38 (2) ratio.
