The crystal structure described by Sr3Au2 crystallizes in the trigonal R-3 space group. There are three inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 5-coordinate geometry to five equivalent Au(1) atoms. In the second Sr site, Sr(2) is bonded in an octahedral geometry to six equivalent Au(1) atoms. In the third Sr site, Sr(3) is bonded in a 6-coordinate geometry to six equivalent Au(1) atoms. Au(1) is bonded in a 8-coordinate geometry to one Sr(2), two equivalent Sr(3), and five equivalent Sr(1) atoms. is represented by the CIF file [CIF]
