mer-Hydridotris(tri­methyl­phosphane-κP)(D-valinato-κ²N,O)iridium hexa­fluorido­phosphate di­chloro­methane 0.675-solvate

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 enanti­omorphic 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.
