Ce3Au crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a distorted see-saw-like geometry to four equivalent Au(1) atoms. In the second Ce site, Ce(2) is bonded in a distorted see-saw-like geometry to four equivalent Au(1) atoms. Au(1) is bonded to four equivalent Ce(2) and eight equivalent Ce(1) atoms to form a mixture of corner and face-sharing AuCe12 cuboctahedra.
Ce3Au crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a distorted see-saw-like geometry to four equivalent Au(1) atoms. There are two shorter (3.17 Å) and two longer (3.36 Å) Ce(1)-Au(1) bond lengths. In the second Ce site, Ce(2) is bonded in a distorted see-saw-like geometry to four equivalent Au(1) atoms. There are two shorter (3.17 Å) and two longer (3.37 Å) Ce(2)-Au(1) bond lengths. Au(1) is bonded to four equivalent Ce(2) and eight equivalent Ce(1) atoms to form a mixture of corner and face-sharing AuCe12 cuboctahedra.
