The structure of the rare hydridohydroxy complex cis-[IrH(OH)(PMe3)4]PF6 has been analyzed at 20 K by single-crystal neutron diffraction. The results confirm the geometry derived from an earlier X-ray analysis. Perhaps the most significant result concerns the bending of the O-H group towards the hydride ligand, with a smaller-than-usual Ir-O-H angle of 104.4(7)°, suggestive of an attractive interaction between the electron-deficient H atom of the hydroxy group and the electronegative hydride ligand.
