Notes: Summary The crystal structure of (PPh4)2[ReO(OH)(CN)4]·5H2O has been determined from three-dimensional x-ray diffraction data. The light brown crystals are monoclinic, space group P21/n, with cell dimensionsa=16.753(2),b=19.928(2),c=15.338(2) Å and β=101,894(1)°,z=4, Dm=1.45(1) g cm−3. The anisotropic refinement of the 6088 observed reflections converged to R=0.077. The [ReO(OH)(CN)4]2− ion has a distorted octahedral geometry. Bond distances: Re =1.70(1), Re−OH=1.90(1) and ReℑCav=2.12(2) Å. The Re atom is displaced by 0.08 Å out of the plane formed by the four carbon atoms towards the terminal oxo ligand.
