The material structure described by SbPO4 crystallizes in the monoclinic C2/c space group. There are three inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 5-coordinate geometry to one O(2), one O(3), one O(4), one O(6), and one O(7) atom. In the second Sb site, Sb(2) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(4) atoms. In the third Sb site, Sb(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent O(5) and two equivalent O(7) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded in a tetrahedral geometry to one O(1), one O(4), one O(7), and one O(8) atom. In the second P site, P(2) is bonded in a tetrahedral geometry to one O(2), one O(3), one O(5), and one O(6) atom. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Sb(2) and one P(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Sb(1) and one P(2) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Sb(1) and one P(2) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Sb(1), one Sb(2), and one P(1) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one Sb(3) and one P(2) atom. In the sixth O site, O(6) is bonded in a distorted single-bond geometry to one Sb(1) and one P(2) atom. In the seventh O site, O(7) is bonded in a distorted single-bond geometry to one Sb(1), one Sb(3), and one P(1) atom. In the eighth O site, O(8) is bonded in a single-bond geometry to one P(1) atom. is represented by the CIF file [CIF]
