Materials Data on SbRhO4 by Materials Project

Abstract

RhSbO4 is Hydrophilite-derived structured and crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. Rh3+ is bonded to six O2- atoms to form RhO6 octahedra that share corners with eight equivalent SbO6 octahedra and edges with two equivalent RhO6 octahedra. The corner-sharing octahedral tilt angles are 52°. All Rh–O bond lengths are 2.05 Å. Sb5+ is bonded to six O2- atoms to form SbO6 octahedra that share corners with eight equivalent RhO6 octahedra and edges with two equivalent SbO6 octahedra. The corner-sharing octahedral tilt angles are 52°. There are two shorter (2.01 Å) and four longer (2.05 Å) Sb–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Rh3+ and one Sb5+ atom. In the second O2- site, O2- is bonded in a trigonal planar geometry to one Rh3+ and two equivalent Sb5+ atoms.
