The material structure described by Sr2(Au2Ga)3 crystallizes in the trigonal R-3c space group. Sr(1) is bonded in a 15-coordinate geometry to twelve equivalent Au(1) and three equivalent Ga(1) atoms. Au(1) is bonded in a 11-coordinate geometry to four equivalent Sr(1), four equivalent Au(1), and three equivalent Ga(1) atoms. Ga(1) is bonded in a 6-coordinate geometry to two equivalent Sr(1) and six equivalent Au(1) atoms. is represented by the CIF file [CIF]
