SbOPO4 crystallizes in the monoclinic C2/c space group. Sb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SbO6 octahedra that share corners with two equivalent Sb(1)O6 octahedra and corners with four equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 45°. P(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form PO4 tetrahedra that share corners with four equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 37-49°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Sb(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to two equivalent Sb(1) atoms. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Sb(1) and one P(1) atom.
