Materials Data on Rh2WO6 by Materials Project

Rh2WO6 is Hydrophilite-derived structured and crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. W6+ is bonded to six O2- atoms to form WO6 octahedra that share corners with eight equivalent RhO6 octahedra and edges with two equivalent RhO6 octahedra. The corner-sharing octahedra tilt angles range from 50–51°. There are two shorter (1.98 Å) and four longer (2.02 Å) W–O bond lengths. Rh3+ is bonded to six O2- atoms to form RhO6 octahedra that share corners with four equivalent WO6 octahedra, corners with four equivalent RhO6 octahedra, an edgeedge with one WO6 octahedra, and an edgeedge with one RhO6 octahedra. The corner-sharing octahedra tilt angles range from 50–52°. There are a spread of Rh–O bond distances ranging from 2.00–2.05 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one W6+ and two equivalent Rh3+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one W6+ and two equivalent Rh3+ atoms.
