Abstract:
The title compound, [Ir(C5H10NO2)H(C3H9P)3]PF6·0.675CH2Cl2, an iridium compound with a meridional arrangement of PMe3 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 enanti-omorphic space groups (P43 and P41, 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 41 screw of the c axis.
