Li2BiO3 is Enargite-like structured and crystallizes in the orthorhombic Cmc2_1 space group. Li(1) is bonded to one O(2) and three equivalent O(1) atoms to form LiO4 tetrahedra that share corners with five equivalent Bi(1)O4 tetrahedra and corners with seven equivalent Li(1)O4 tetrahedra. Bi(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form BiO4 tetrahedra that share corners with two equivalent Bi(1)O4 tetrahedra and corners with ten equivalent Li(1)O4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Li(1) and one Bi(1) atom to form OLi3Bi tetrahedra that share corners with five equivalent O(2)Li2Bi2 tetrahedra and corners with seven equivalent O(1)Li3Bi tetrahedra. In the second O site, O(2) is bonded to two equivalent Li(1) and two equivalent Bi(1) atoms to form OLi2Bi2 tetrahedra that share corners with two equivalent O(2)Li2Bi2 tetrahedra and corners with ten equivalent O(1)Li3Bi tetrahedra.

Li(1) is bonded to one O(2) and three equivalent O(1) atoms to form LiO4 tetrahedra that share corners with five equivalent Bi(1)O4 tetrahedra and corners with seven equivalent Li(1)O4 tetrahedra. The Li(1)-O(2) bond length is 2.14 Å. There are two shorter (2.00 Å) and one longer (2.02 Å) Li(1)-O(1) bond length. Bi(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form BiO4 tetrahedra that share corners with two equivalent Bi(1)O4 tetrahedra and corners with ten equivalent Li(1)O4 tetrahedra. Both Bi(1)-O(1) bond lengths are 2.09 Å. There is one shorter (2.17 Å) and one longer (2.26 Å) Bi(1)-O(2) bond length. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Li(1) and one Bi(1) atom to form OLi3Bi tetrahedra that share corners with five equivalent O(2)Li2Bi2 tetrahedra and corners with seven equivalent O(1)Li3Bi tetrahedra.
