The material structure described by Co(PO3)4 crystallizes in the monoclinic C2/c space group. Co(1) is bonded to two equivalent O(3), two equivalent O(4), and two equivalent O(5) 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(5), one O(6), and one O(7) atom to form PO4 tetrahedra that share  a cornercorner with one Co(1)O6 octahedra,  a cornercorner with one P(1)O4 tetrahedra, and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles are 48°. In the second P site, P(2) is bonded to one O(2), one O(3), one O(4), and one O(7) atom to form PO4 tetrahedra that share corners with two equivalent Co(1)O6 octahedra,  a cornercorner with one P(1)O4 tetrahedra, and  a cornercorner with one P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 44-49°. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one P(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to two equivalent P(2) atoms. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Co(1) and one P(2) atom. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Co(1) and one P(2) atom. In the fifth O site, O(5) is bonded in a distorted bent 120 degrees geometry to one Co(1) and one P(1) atom. In the sixth O site, O(6) is bonded in a bent 120 degrees geometry to two equivalent P(1) atoms. In the seventh O site, O(7) is bonded in a bent 150 degrees geometry to one P(1) and one P(2) atom. is represented by the CIF file [CIF]
