Au2Al crystallizes in the orthorhombic Pnma space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 5-coordinate geometry to five equivalent Al(1) atoms. In the second Au site, Au(2) is bonded in a 4-coordinate geometry to four equivalent Al(1) atoms. Al(1) is bonded in a distorted q6 geometry to four equivalent Au(2) and five equivalent Au(1) atoms.
Au2Al crystallizes in the orthorhombic Pnma space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 5-coordinate geometry to five equivalent Al(1) atoms. There are a spread of Au(1)-Al(1) bond distances ranging from 2.68-2.84 Å. In the second Au site, Au(2) is bonded in a 4-coordinate geometry to four equivalent Al(1) atoms. There are two shorter (2.63 Å) and two longer (2.69 Å) Au(2)-Al(1) bond lengths. Al(1) is bonded in a distorted q6 geometry to four equivalent Au(2) and five equivalent Au(1) atoms.
