The material described by Hf7Au10 crystallizes in the orthorhombic Cmce space group. There are four inequivalent Hf sites. In the first Hf site, Hf(1) is bonded in a 10-coordinate geometry to two equivalent Au(3), four equivalent Au(1), and four equivalent Au(2) atoms. In the second Hf site, Hf(2) is bonded in a distorted body-centered cubic geometry to four equivalent Au(1) and four equivalent Au(2) atoms. In the third Hf site, Hf(3) is bonded in a 8-coordinate geometry to four equivalent Au(1) and four equivalent Au(2) atoms. In the fourth Hf site, Hf(4) is bonded in a 7-coordinate geometry to two equivalent Au(1), two equivalent Au(2), and three equivalent Au(3) atoms. There are three inequivalent Au sites. In the first Au site, Au(2) is bonded in a 6-coordinate geometry to one Hf(2), one Hf(4), two equivalent Hf(1), and two equivalent Hf(3) atoms. In the second Au site, Au(3) is bonded in a 5-coordinate geometry to two equivalent Hf(1) and three equivalent Hf(4) atoms. In the third Au site, Au(1) is bonded in a 6-coordinate geometry to one Hf(2), one Hf(4), two equivalent Hf(1), and two equivalent Hf(3) atoms. is represented by the CIF card [CIF]
