The material described by Mo2(PO4)3 crystallizes in the triclinic P-1 space group. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to one O(1), one O(12), one O(2), one O(5), one O(8), and one O(9) atom to form MoO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra, corners with two equivalent P(2)O4 tetrahedra, and corners with two equivalent P(3)O4 tetrahedra. In the second Mo site, Mo(2) is bonded to one O(10), one O(11), one O(3), one O(4), one O(6), and one O(7) atom to form MoO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra, corners with two equivalent P(2)O4 tetrahedra, and corners with two equivalent P(3)O4 tetrahedra. There are three inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(3), one O(7), and one O(8) atom to form PO4 tetrahedra that share corners with two equivalent Mo(1)O6 octahedra and corners with two equivalent Mo(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 24-28°. In the second P site, P(2) is bonded to one O(10), one O(11), one O(12), and one O(9) atom to form PO4 tetrahedra that share corners with two equivalent Mo(1)O6 octahedra and corners with two equivalent Mo(2)O6 octahedra.

The corner-sharing octahedral tilt angles range from 22-31°. There are twelve inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Mo(1) and one P(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Mo(1) and one P(3) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one Mo(2) and one P(1) atom.
