The structure described by Li2Cu(PO3)4 crystallizes in the monoclinic C2/c space group. Li(1) is bonded in a 5-coordinate geometry to one O(2), one O(3), one O(5), and two equivalent O(6) atoms. Cu(1) is bonded in a distorted square co-planar geometry to two equivalent O(2) and two equivalent O(5) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(4), one O(5), one O(6), and one O(7) atom to form corner-sharing PO4 tetrahedra. In the second P site, P(2) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form corner-sharing PO4 tetrahedra. There are seven inequivalent O sites. In the first O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Li(1) and one P(2) atom. In the second O site, O(4) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the third O site, O(5) is bonded in a distorted trigonal planar geometry to one Li(1), one Cu(1), and one P(1) atom. In the fourth O site, O(6) is bonded in a distorted trigonal planar geometry to two equivalent Li(1) and one P(1) atom. In the fifth O site, O(7) is bonded in a bent 120 degrees geometry to two equivalent P(1) atoms. In the sixth O site, O(1) is bonded in a bent 120 degrees geometry to two equivalent P(2) atoms. In the seventh O site, O(2) is bonded in a 2-coordinate geometry to one Li(1), one Cu(1), and one P(2) atom. is represented by the CIF file [CIF]
