The material described by Sr2V(PO4)3 crystallizes in the monoclinic C2/c space group. Sr(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(3), one O(4), one O(6), and three equivalent O(5) atoms. V(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form VO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with four equivalent P(2)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to two equivalent O(1) and two equivalent O(4) atoms to form PO4 tetrahedra that share corners with two equivalent V(1)O6 octahedra. The corner-sharing octahedral tilt angles are 22°. In the second P site, P(2) is bonded to one O(2), one O(3), one O(5), and one O(6) atom to form PO4 tetrahedra that share corners with two equivalent V(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-43°. There are six inequivalent O sites. In the first O site, O(3) is bonded in a 3-coordinate geometry to one Sr(1), one V(1), and one P(2) atom. In the second O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Sr(1) and one P(1) atom. In the third O site, O(5) is bonded in a 1-coordinate geometry to three equivalent Sr(1) and one P(2) atom. In the fourth O site, O(6) is bonded in a bent 150 degrees geometry to one Sr(1) and one P(2) atom. In the fifth O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Sr(1), one V(1), and one P(1) atom. In the sixth O site, O(2) is bonded in a 3-coordinate geometry to one Sr(1), one V(1), and one P(2) atom. is represented by the CIF file [CIF]
