Materials Data on U(RhO3)2 by Materials Project
Abstract
U(RhO3)2 is Hydrophilite-derived structured and crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. U6+ is bonded to six O2- atoms to form UO6 octahedra that share corners with eight equivalent RhO6 octahedra and edges with two equivalent RhO6 octahedra. The corner-sharing octahedra tilt angles range from 48–51°. There are four shorter (2.09 Å) and two longer (2.13 Å) U–O bond lengths. Rh3+ is bonded to six O2- atoms to form RhO6 octahedra that share corners with four equivalent UO6 octahedra, corners with four equivalent RhO6 octahedra, an edgeedge with one UO6 octahedra, and an edgeedge with one RhO6 octahedra. The corner-sharing octahedra tilt angles range from 48–51°. There are a spread of Rh–O bond distances ranging from 2.04–2.06 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one U6+ and two equivalent Rh3+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one U6+ and two equivalent Rh3+ atoms.
