The material structure described by RhNbO4 is Hydrophilite-derived structured and crystallizes in the orthorhombic Cmmm space group. Nb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form NbO6 octahedra that share corners with eight equivalent Rh(1)O6 octahedra and edges with two equivalent Nb(1)O6 octahedra. The corner-sharing octahedral tilt angles are 50°. 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 Nb(1)O6 octahedra and edges with two equivalent Rh(1)O6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to two equivalent Nb(1) and one Rh(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Nb(1) and two equivalent Rh(1) atoms. is represented by the CIF card [CIF]
