The material structure described by Au7P10I crystallizes in the trigonal P-31m space group. There are three inequivalent Au sites. In the first Au site, Au(1) is bonded to three equivalent P(1) and one I(1) atom to form distorted AuP3I trigonal pyramids that share corners with six equivalent P(2)P3Au tetrahedra and  a cornercorner with one Au(1)P3I trigonal pyramid. In the second Au site, Au(2) is bonded in a linear geometry to two equivalent P(1) atoms. In the third Au site, Au(3) is bonded in a linear geometry to two equivalent P(2) atoms. There are two inequivalent P sites. In the first P site, P(1) is bonded to one Au(1), one Au(2), and two equivalent P(2) atoms to form corner-sharing PP2Au2 tetrahedra. In the second P site, P(2) is bonded to one Au(3) and three equivalent P(1) atoms to form distorted PP3Au tetrahedra that share corners with four equivalent P(2)P3Au tetrahedra and corners with three equivalent Au(1)P3I trigonal pyramids. I(1) is bonded in a linear geometry to two equivalent Au(1) atoms. is represented by the CIF file [CIF]
