The material described by Li3Sb2(PO4)3 crystallizes in the monoclinic C2/c space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 4-coordinate geometry to one O(1), one O(3), one O(4), and one O(6) atom. In the second Li site, Li(2) is bonded in a distorted rectangular see-saw-like geometry to two equivalent O(5) and two equivalent O(6) atoms. Sb(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form distorted SbO6 octahedra that share corners with two equivalent P(2)O4 tetrahedra and corners with four equivalent P(1)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(1), one O(2), one O(4), and one O(5) atom to form PO4 tetrahedra that share corners with four equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 19-64°. In the second P site, P(2) is bonded to two equivalent O(3) and two equivalent O(6) atoms to form PO4 tetrahedra that share corners with four equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 40-53°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Li(1), one Sb(1), and one P(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Sb(1) and one P(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Li(1), one Sb(1), and one P(2) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Li(1), one Sb(1), and one P(1) atom. In the fifth O site, O(5) is bonded in a distorted bent 150 degrees geometry to one Li(2), one Sb(1), and one P(1) atom. In the sixth O site, O(6) is bonded in a distorted rectangular see-saw-like geometry to one Li(1), one Li(2), one Sb(1), and one P(2) atom. is represented by the CIF card [CIF]
