The crystal structure described by Li2PbO3 crystallizes in the monoclinic C2/c space group. There are three inequivalent Li sites. In the first Li site, Li(1) is bonded in a rectangular see-saw-like geometry to one O(2), one O(3), and two equivalent O(1) atoms. In the second Li site, Li(2) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. In the third Li site, Li(3) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(3) atoms. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(3), and four equivalent O(2) atoms. In the second Pb site, Pb(2) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 6-coordinate geometry to one Li(2), one Li(3), two equivalent Li(1), one Pb(1), and one Pb(2) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one Li(1), one Li(2), one Pb(2), and two equivalent Pb(1) atoms. In the third O site, O(3) is bonded in a 5-coordinate geometry to one Li(1), one Li(2), one Li(3), one Pb(1), and one Pb(2) atom. is represented by the CIF card [CIF]
