Li3SbO3 crystallizes in the cubic P2_13 space group. There are three inequivalent Li sites. In the first Li site, Li(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. In the second Li site, Li(2) is bonded in a distorted trigonal planar geometry to three equivalent O(1) atoms. In the third Li site, Li(3) is bonded in a trigonal non-coplanar geometry to three equivalent O(1) atoms. Sb(1) is bonded in a 3-coordinate geometry to three equivalent O(1) atoms. O(1) is bonded to one Li(1), one Li(2), one Li(3), and one Sb(1) atom to form corner-sharing OLi3Sb tetrahedra.
