The material structure described by Cu5Zn8 is gamma-brass structured and crystallizes in the cubic I-43m space group. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 9-coordinate geometry to three equivalent Cu(2), three equivalent Zn(1), and six equivalent Zn(2) atoms. In the second Cu site, Cu(2) is bonded in a 13-coordinate geometry to one Cu(2), two equivalent Cu(1), two equivalent Zn(1), and eight equivalent Zn(2) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 12-coordinate geometry to three equivalent Cu(1), three equivalent Cu(2), three equivalent Zn(1), and three equivalent Zn(2) atoms. In the second Zn site, Zn(2) is bonded in a 11-coordinate geometry to two equivalent Cu(1), four equivalent Cu(2), one Zn(1), and four equivalent Zn(2) atoms. is represented by the CIF card [CIF]
