SbOPO4 crystallizes in the orthorhombic Fdd2 space group. Sb(1) is bonded to one O(1), one O(3), one O(4), one O(5), and two equivalent O(2) 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 51°. P(1) is bonded to one O(1), one O(3), one O(4), and one O(5) atom to form PO4 tetrahedra that share corners with four equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 37-56°. There are five 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(3) is bonded in a bent 120 degrees geometry to one Sb(1) and one P(1) atom. In the third O site, O(2) is bonded in a bent 120 degrees geometry to two equivalent Sb(1) atoms. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Sb(1) and one P(1) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one Sb(1) and one P(1) atom.
