The crystal structure described by RhAsO4 is Hydrophilite-derived structured and crystallizes in the orthorhombic Cmmm space group. Rh(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form RhO6 octahedra that share corners with eight equivalent As(1)O6 octahedra and edges with two equivalent Rh(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-52°. As(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form AsO6 octahedra that share corners with eight equivalent Rh(1)O6 octahedra and edges with two equivalent As(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-52°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Rh(1) and two equivalent As(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Rh(1) and one As(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
