The material described by Li2Bi2(SO4)3 crystallizes in the monoclinic C2/c space group. Li(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form LiO4 tetrahedra that share  a cornercorner with one S(2)O4 tetrahedra, corners with three equivalent S(1)O4 tetrahedra, and  an edgeedge with one Li(1)O4 tetrahedra. Bi(1) is bonded in a 4-coordinate geometry to one O(1), one O(4), one O(5), and one O(6) atom. There are two inequivalent S sites. In the first S site, S(1) is bonded to one O(2), one O(3), one O(4), and one O(6) atom to form SO4 tetrahedra that share corners with three equivalent Li(1)O4 tetrahedra. In the second S site, S(2) is bonded to two equivalent O(1) and two equivalent O(5) atoms to form SO4 tetrahedra that share corners with two equivalent Li(1)O4 tetrahedra. There are six inequivalent O sites. In the first O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Bi(1) and one S(1) atom. In the second O site, O(5) is bonded in a distorted bent 150 degrees geometry to one Bi(1) and one S(2) atom. In the third O site, O(6) is bonded in a 2-coordinate geometry to one Bi(1) and one S(1) atom. In the fourth O site, O(1) is bonded in a distorted trigonal planar geometry to one Li(1), one Bi(1), and one S(2) atom. In the fifth O site, O(2) is bonded in a distorted T-shaped geometry to two equivalent Li(1) and one S(1) atom. In the sixth O site, O(3) is bonded in a bent 120 degrees geometry to one Li(1) and one S(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
