The crystal structure described by Au5Sr crystallizes in the hexagonal P6/mmm space group. Sr(1) is bonded in a distorted hexagonal planar geometry to six equivalent Au(1) and twelve equivalent Au(2) atoms. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a 3-coordinate geometry to three equivalent Sr(1) and six equivalent Au(2) atoms. In the second Au site, Au(2) is bonded to four equivalent Sr(1), four equivalent Au(1), and four equivalent Au(2) atoms to form a mixture of corner, edge, and face-sharing AuSr4Au8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
