The structure described by Sm3AuO6 crystallizes in the triclinic P-1 space group. There are two inequivalent Sm sites. In the first Sm site, Sm(1) is bonded in a 7-coordinate geometry to two equivalent O(2), two equivalent O(3), and three equivalent O(1) atoms. In the second Sm site, Sm(2) is bonded in a 6-coordinate geometry to two equivalent O(3) and four equivalent O(2) atoms. Au(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to three equivalent Sm(1) and one Au(1) atom. In the second O site, O(2) is bonded to two equivalent Sm(1) and two equivalent Sm(2) atoms to form OSm4 tetrahedra that share corners with four equivalent O(3)Sm3Au tetrahedra, corners with four equivalent O(2)Sm4 tetrahedra, edges with two equivalent O(3)Sm3Au tetrahedra, and edges with two equivalent O(2)Sm4 tetrahedra. In the third O site, O(3) is bonded to one Sm(2), two equivalent Sm(1), and one Au(1) atom to form OSm3Au tetrahedra that share corners with four equivalent O(3)Sm3Au tetrahedra, corners with four equivalent O(2)Sm4 tetrahedra, and edges with two equivalent O(2)Sm4 tetrahedra. is represented by the CIF file [CIF]
