CrTaO4 is Hydrophilite-derived structured and crystallizes in the monoclinic P2/m space group. Ta(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form TaO6 octahedra that share corners with eight equivalent Cr(1)O6 octahedra and edges with two equivalent Ta(1)O6 octahedra. The corner-sharing octahedral tilt angles are 50°. Cr(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CrO6 octahedra that share corners with eight equivalent Ta(1)O6 octahedra and edges with two equivalent Cr(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 Ta(1) and one Cr(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Ta(1) and two equivalent Cr(1) atoms.
