Li2Co(PO3)4 crystallizes in the monoclinic P2_1/c space group. Li(1) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(3), and one O(6) atom. Co(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(6) atoms to form CoO6 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 one O(1), one O(4), one O(5), and one O(6) atom to form PO4 tetrahedra that share  a cornercorner with one Co(1)O6 octahedra and corners with two equivalent P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles are 34°. In the second P site, P(2) is bonded to one O(2), one O(3), one O(4), and one O(5) atom to form PO4 tetrahedra that share corners with two equivalent Co(1)O6 octahedra and corners with two equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 11-37°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Li(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to one Co(1) and one P(2) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Li(1), one Co(1), and one P(2) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one P(1) and one P(2) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one P(1) and one P(2) atom. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to one Li(1), one Co(1), and one P(1) atom.
