Ce2Au3Sb crystallizes in the orthorhombic Pmm2 space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to two equivalent Au(3), four equivalent Au(1), four equivalent Au(2), and two equivalent Sb(1) atoms to form distorted CeSb2Au10 cuboctahedra that share edges with four equivalent Ce(1)Sb2Au10 cuboctahedra, edges with eight equivalent Ce(2)Sb4Au8 cuboctahedra, faces with four equivalent Ce(1)Sb2Au10 cuboctahedra, and faces with four equivalent Ce(2)Sb4Au8 cuboctahedra. In the second Ce site, Ce(2) is bonded to two equivalent Au(1), two equivalent Au(2), four equivalent Au(3), and four equivalent Sb(1) atoms to form distorted CeSb4Au8 cuboctahedra that share edges with four equivalent Ce(2)Sb4Au8 cuboctahedra, edges with eight equivalent Ce(1)Sb2Au10 cuboctahedra, faces with four equivalent Ce(1)Sb2Au10 cuboctahedra, and faces with four equivalent Ce(2)Sb4Au8 cuboctahedra. There are three inequivalent Au sites. In the first Au site, Au(1) is bonded in a 9-coordinate geometry to two equivalent Ce(2), four equivalent Ce(1), one Au(2), and two equivalent Au(3) atoms. In the second Au site, Au(2) is bonded in a 9-coordinate geometry to two equivalent Ce(2), four equivalent Ce(1), one Au(1), and two equivalent Sb(1) atoms. In the third Au site, Au(3) is bonded in a 9-coordinate geometry to two equivalent Ce(1), four equivalent Ce(2), two equivalent Au(1), and one Sb(1) atom. Sb(1) is bonded in a 9-coordinate geometry to two equivalent Ce(1), four equivalent Ce(2), one Au(3), and two equivalent Au(2) atoms.
