The crystal structure described by Sr2(Au2Zn)3 crystallizes in the trigonal R-3c space group. Sr(1) is bonded in a 9-coordinate geometry to twelve equivalent Au(1) atoms. Au(1) is bonded in a 11-coordinate geometry to four equivalent Sr(1), four equivalent Au(1), and three equivalent Zn(1) atoms. Zn(1) is bonded in a 6-coordinate geometry to six equivalent Au(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
