Au3In is beta Cu3Ti structured and crystallizes in the orthorhombic Pmmn space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a distorted see-saw-like geometry to eight equivalent Au(2) and four equivalent In(1) atoms. In the second Au site, Au(2) is bonded to four equivalent Au(1), four equivalent Au(2), and four equivalent In(1) atoms to form distorted AuIn4Au8 cuboctahedra that share corners with four equivalent In(1)Au12 cuboctahedra, corners with ten equivalent Au(2)In4Au8 cuboctahedra, edges with six equivalent Au(2)In4Au8 cuboctahedra, edges with six equivalent In(1)Au12 cuboctahedra, faces with four equivalent In(1)Au12 cuboctahedra, and faces with twelve equivalent Au(2)In4Au8 cuboctahedra. In(1) is bonded to four equivalent Au(1) and eight equivalent Au(2) atoms to form InAu12 cuboctahedra that share corners with two equivalent In(1)Au12 cuboctahedra, corners with eight equivalent Au(2)In4Au8 cuboctahedra, edges with six equivalent In(1)Au12 cuboctahedra, edges with twelve equivalent Au(2)In4Au8 cuboctahedra, faces with six equivalent In(1)Au12 cuboctahedra, and faces with eight equivalent Au(2)In4Au8 cuboctahedra.
Au3In is beta Cu3Ti structured and crystallizes in the orthorhombic Pmmn space group. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a distorted see-saw-like geometry to eight equivalent Au(2) and four equivalent In(1) atoms. There are four shorter (2.97 Å) and four longer (3.00 Å) Au(1)-Au(2) bond lengths. There are two shorter (2.89 Å) and two longer (2.97 Å) Au(1)-In(1) bond lengths. In the second Au site, Au(2) is bonded to four equivalent Au(1), four equivalent Au(2), and four equivalent In(1) atoms to form distorted AuIn4Au8 cuboctahedra that share corners with four equivalent In(1)Au12 cuboctahedra, corners with ten equivalent Au(2)In4Au8 cuboctahedra, edges with six equivalent Au(2)In4Au8 cuboctahedra, edges with six equivalent In(1)Au12 cuboctahedra, faces with four equivalent In(1)Au12 cuboctahedra, and faces with twelve equivalent Au(2)In4Au8 cuboctahedra. There are a spread of Au(2)-Au(2) bond distances ranging from 2.87-2.97 Å. There are a spread of Au(2)-In(1) bond distances ranging from 2.96-3.02 Å. In(1) is bonded to four equivalent Au(1) and eight equivalent Au(2) atoms to form InAu12 cuboctahedra that share corners with two equivalent In(1)Au12 cuboctahedra, corners with eight equivalent Au(2)In4Au8 cuboctahedra, edges with six equivalent In(1)Au12 cuboctahedra, edges with twelve equivalent Au(2)In4Au8 cuboctahedra, faces with six equivalent In(1)Au12 cuboctahedra, and faces with eight equivalent Au(2)In4Au8 cuboctahedra.
