LiSiBiO4 crystallizes in the orthorhombic Pna2_1 space group. Li(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form LiO4 tetrahedra that share corners with four equivalent Si(1)O4 tetrahedra. Si(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form SiO4 tetrahedra that share corners with four equivalent Li(1)O4 tetrahedra. Bi(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one Li(1), one Si(1), and one Bi(1) atom. In the second O site, O(2) is bonded in a trigonal non-coplanar geometry to one Li(1), one Si(1), and one Bi(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Li(1), one Si(1), and one Bi(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Li(1), one Si(1), and one Bi(1) atom.
