TaRhO4 is beta Vanadium nitride-derived structured and crystallizes in the tetragonal I4_1md space group. Ta(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form TaO6 octahedra that share corners with four equivalent Ta(1)O6 octahedra, corners with four equivalent Rh(1)O6 octahedra, and edges with two equivalent Rh(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 44-50°. Rh(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form RhO6 octahedra that share corners with four equivalent Ta(1)O6 octahedra, corners with four equivalent Rh(1)O6 octahedra, and edges with two equivalent Ta(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 44-51°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Ta(1) and two equivalent Rh(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Ta(1) and one Rh(1) atom.

The corner-sharing octahedral tilt angles range from 44-50°. Both Ta(1)-O(1) bond lengths are 1.93 Å. There are two shorter (2.02 Å) and two longer (2.03 Å) Ta(1)-O(2) bond lengths. Rh(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form RhO6 octahedra that share corners with four equivalent Ta(1)O6 octahedra, corners with four equivalent Rh(1)O6 octahedra, and edges with two equivalent Ta(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 44-51°. Both Rh(1)-O(2) bond lengths are 2.04 Å. There are two shorter (2.00 Å) and two longer (2.07 Å) Rh(1)-O(1) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Ta(1) and two equivalent Rh(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Ta(1) and one Rh(1) atom.
