The material described by Co(PO3)2 crystallizes in the monoclinic C2/c space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(5) atoms to form CoO6 octahedra that share corners with two equivalent P(2)O4 tetrahedra, corners with four equivalent P(1)O4 tetrahedra, and edges with two equivalent Co(2)O6 octahedra. In the second Co site, Co(2) is bonded to two equivalent O(2), two equivalent O(4), and two equivalent O(5) atoms to form CoO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra, corners with four equivalent P(2)O4 tetrahedra, and edges with two equivalent Co(1)O6 octahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(3), and one O(6) atom to form PO4 tetrahedra that share  a cornercorner with one Co(2)O6 octahedra, corners with two equivalent Co(1)O6 octahedra, and corners with two equivalent P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 23-58°. In the second P site, P(2) is bonded to one O(3), 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, corners with two equivalent Co(2)O6 octahedra, and corners with two equivalent P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 22-59°. There are six inequivalent O sites. In the first O site, O(3) is bonded in a bent 150 degrees geometry to one P(1) and one P(2) atom. In the second O site, O(4) is bonded in a bent 150 degrees geometry to one Co(2) and one P(2) atom. In the third O site, O(5) is bonded in a distorted trigonal planar geometry to one Co(1), one Co(2), and one P(2) atom. In the fourth O site, O(6) is bonded in a distorted bent 150 degrees geometry to one P(1) and one P(2) atom. In the fifth O site, O(1) is bonded in a bent 150 degrees geometry to one Co(1) and one P(1) atom. In the sixth O site, O(2) is bonded in a distorted trigonal planar geometry to one Co(1), one Co(2), and one P(1) atom. is represented by the CIF file [CIF]
