The material described by LiSiBiO4 is Ilmenite-derived structured and crystallizes in the orthorhombic Pnma space group. Li(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form LiO6 octahedra that share corners with four equivalent Bi(1)O6 pentagonal pyramids, corners with two equivalent Si(1)O4 tetrahedra, edges with two equivalent Li(1)O6 octahedra, edges with two equivalent Bi(1)O6 pentagonal pyramids, and edges with two equivalent Si(1)O4 tetrahedra. Si(1) is bonded to one O(1), one O(3), and two equivalent O(2) atoms to form SiO4 tetrahedra that share corners with two equivalent Li(1)O6 octahedra, corners with four equivalent Bi(1)O6 pentagonal pyramids, edges with two equivalent Li(1)O6 octahedra, and  an edgeedge with one Bi(1)O6 pentagonal pyramid. The corner-sharing octahedral tilt angles are 54°. Bi(1) is bonded to one O(1), one O(3), and four equivalent O(2) atoms to form BiO6 pentagonal pyramids that share corners with four equivalent Li(1)O6 octahedra, corners with four equivalent Bi(1)O6 pentagonal pyramids, corners with four equivalent Si(1)O4 tetrahedra, edges with two equivalent Li(1)O6 octahedra, and  an edgeedge with one Si(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 55-74°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Li(1), one Si(1), and one Bi(1) atom to form distorted corner-sharing OLi2SiBi trigonal pyramids. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to one Li(1), one Si(1), and two equivalent Bi(1) atoms. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Li(1), one Si(1), and one Bi(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
