The structure described by LiCo2(PO4)2 crystallizes in the monoclinic C2 space group. Li(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form LiO4 tetrahedra that share corners with two equivalent Co(1)O4 tetrahedra, corners with two equivalent Co(2)O4 tetrahedra, and corners with four equivalent P(1)O4 tetrahedra. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent O(2) and two equivalent O(3) atoms to form CoO4 tetrahedra that share corners with two equivalent Li(1)O4 tetrahedra and corners with four equivalent P(1)O4 tetrahedra. In the second Co site, Co(2) is bonded to two equivalent O(1) and two equivalent O(4) atoms to form CoO4 tetrahedra that share corners with two equivalent Li(1)O4 tetrahedra and corners with four equivalent P(1)O4 tetrahedra. P(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form PO4 tetrahedra that share corners with two equivalent Li(1)O4 tetrahedra, corners with two equivalent Co(1)O4 tetrahedra, and corners with two equivalent Co(2)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Li(1), one Co(2), and one P(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Co(1) and one P(1) atom. In the third O site, O(3) is bonded in a trigonal non-coplanar geometry to one Li(1), one Co(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one Co(2) and one P(1) atom. is represented by the CIF file [CIF]
