The structure described by SrAu3Al2 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded in a 10-coordinate geometry to three equivalent Au(1), three equivalent Au(3), and four equivalent Au(2) atoms. There are three inequivalent Au sites. In the first Au site, Au(1) is bonded in a 4-coordinate geometry to three equivalent Sr(1) and four equivalent Al(1) atoms. In the second Au site, Au(2) is bonded in a 2-coordinate geometry to four equivalent Sr(1) and four equivalent Al(1) atoms. In the third Au site, Au(3) is bonded in a 2-coordinate geometry to three equivalent Sr(1) and four equivalent Al(1) atoms. Al(1) is bonded in a 6-coordinate geometry to two equivalent Au(1), two equivalent Au(2), and two equivalent Au(3) atoms. is represented by the CIF file [CIF]
