LiCo2P3O10 crystallizes in the monoclinic C2/c space group. Li(1) is bonded to two equivalent O(4) and two equivalent O(5) atoms to form distorted LiO4 trigonal pyramids that share corners with four equivalent P(1)O4 tetrahedra and edges with two equivalent Co(1)O4 tetrahedra. Co(1) is bonded to one O(2), one O(3), one O(4), and one O(5) atom to form distorted CoO4 tetrahedra that share  a cornercorner with one P(2)O4 tetrahedra, corners with three equivalent P(1)O4 tetrahedra, and  an edgeedge with one Li(1)O4 trigonal pyramid. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(3), one O(4), and one O(5) atom to form PO4 tetrahedra that share  a cornercorner with one P(2)O4 tetrahedra, corners with three equivalent Co(1)O4 tetrahedra, and corners with two equivalent Li(1)O4 trigonal pyramids. In the second P site, P(2) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form PO4 tetrahedra that share corners with two equivalent Co(1)O4 tetrahedra and corners with two equivalent P(1)O4 tetrahedra. There are five inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Co(1) and one P(2) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Co(1) and one P(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Li(1), one Co(1), and one P(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to one Li(1), one Co(1), and one P(1) atom.
