SrV2(PO5)2 crystallizes in the orthorhombic Fdd2 space group. Sr(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), two equivalent O(3), and two equivalent O(5) atoms. V(1) is bonded to one O(1), one O(2), one O(3), one O(5), and two equivalent O(4) atoms to form VO6 octahedra that share corners with two equivalent V(1)O6 octahedra and corners with four equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 40°. P(1) is bonded to one O(1), one O(2), one O(3), and one O(5) atom to form PO4 tetrahedra that share corners with four equivalent V(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 36-56°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Sr(1), one V(1), and one P(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Sr(1), one V(1), and one P(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Sr(1), one V(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to two equivalent V(1) atoms. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one Sr(1), one V(1), and one P(1) atom.
