The title compound, [Ir(C 5 H 10 NO 2 )H(C 3 H 9 P) 3 ]PF 6 ·0.675CH 2 Cl 2 , an iridium compound with a meridional arrangement of PMe 3  groups,  O , N -bidentate coordination of  d -valine and with a hydride ligand  trans  to the N atom is compared with the  l -valine complex reported previously. As expected, the complexes from the corresponding  l  and  d  isomers of valine crystallize in enanti­omorphic space groups ( P 4 3  and  P 4 1 , respectively). In the crystal, N—H⋯O and N—H⋯F hydrogen bonding is observed, the N—H to carbonyl oxygen hydrogen bond producing a helical motif that proceeds along the 4 1  screw of the  c  axis.
