La4LiAuO8 crystallizes in the orthorhombic Cmmm space group. Li(1) is bonded in a square co-planar geometry to four equivalent O(2) atoms. There are two inequivalent La sites. In the first La site, La(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. In the second La site, La(2) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. Au(1) is bonded in a square co-planar geometry to four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent La(1) and two equivalent La(2) atoms to form OLa4 tetrahedra that share corners with twelve equivalent O(2)LiLa4Au octahedra, corners with four equivalent O(1)La4 tetrahedra, edges with two equivalent O(2)LiLa4Au octahedra, and edges with four equivalent O(1)La4 tetrahedra. The corner-sharing octahedral tilt angles range from 11-69°. In the second O site, O(2) is bonded to one Li(1), two equivalent La(1), two equivalent La(2), and one Au(1) atom to form distorted OLiLa4Au octahedra that share corners with two equivalent O(2)LiLa4Au octahedra, corners with twelve equivalent O(1)La4 tetrahedra, edges with two equivalent O(2)LiLa4Au octahedra, edges with two equivalent O(1)La4 tetrahedra, and faces with four equivalent O(2)LiLa4Au octahedra. The corner-sharing octahedra are not tilted.
