The material structure described by LiCuPO4 crystallizes in the monoclinic Pc space group. Li(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form LiO4 tetrahedra that share corners with four equivalent Cu(1)O4 tetrahedra and corners with four equivalent P(1)O4 tetrahedra. Cu(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form CuO4 tetrahedra that share corners with four 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 four equivalent Li(1)O4 tetrahedra and corners with four equivalent Cu(1)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 Cu(1), and one P(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Li(1), one Cu(1), and one P(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Li(1), one Cu(1), and one P(1) atom. In the fourth O site, O(4) is bonded in a trigonal non-coplanar geometry to one Li(1), one Cu(1), and one P(1) atom. is represented by the CIF card [CIF]
