N,O)tris(trimethylphosphane-κP) iridium(III) hexafluoridophosphate
The title complex, [Ir(C5H8NO2)H(C3H9P)3]PF6, 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(CH3)3 ligands, N,O-bidentate coordination of prolinate and a hydride ligand trans to the prolinate N atom. The independent IrIII moieties are joined by N - HO hydrogen bonds and the N - HO bonding motif continues throughout the structure, creating an extended chain parallel to the c-axis direction. The methyl groups of one P(CH3)3 ligand are rotationally disordered over two sets of sites in a 0.62(2):0.38(2) ratio. © Merola and Roy 2014.
