The crystal structure described by La2Au3Sb crystallizes in the orthorhombic Pmm2 space group. There are two inequivalent La sites. In the first La site, La(1) is bonded to two equivalent Au(3), four equivalent Au(1), four equivalent Au(2), and two equivalent Sb(1) atoms to form LaSb2Au10 cuboctahedra that share edges with four equivalent La(1)Sb2Au10 cuboctahedra, edges with eight equivalent La(2)Sb4Au8 cuboctahedra, faces with four equivalent La(1)Sb2Au10 cuboctahedra, and faces with four equivalent La(2)Sb4Au8 cuboctahedra. In the second La site, La(2) is bonded to two equivalent Au(1), two equivalent Au(2), four equivalent Au(3), and four equivalent Sb(1) atoms to form LaSb4Au8 cuboctahedra that share edges with four equivalent La(2)Sb4Au8 cuboctahedra, edges with eight equivalent La(1)Sb2Au10 cuboctahedra, faces with four equivalent La(1)Sb2Au10 cuboctahedra, and faces with four equivalent La(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 La(2), four equivalent La(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 La(2), four equivalent La(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 La(1), four equivalent La(2), two equivalent Au(1), and one Sb(1) atom. Sb(1) is bonded in a 9-coordinate geometry to two equivalent La(1), four equivalent La(2), one Au(3), and two equivalent Au(2) atoms. is represented by the CIF file [CIF]
