The structure described by Co2Zn11 crystallizes in the cubic I-43m space group. Co(1) is bonded in a distorted q6 geometry to three equivalent Zn(1), three equivalent Zn(2), and six equivalent Zn(3) atoms. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 13-coordinate geometry to two equivalent Co(1), one Zn(1), two equivalent Zn(2), and eight equivalent Zn(3) atoms. In the second Zn site, Zn(3) is bonded in a 2-coordinate geometry to two equivalent Co(1), one Zn(2), and four equivalent Zn(1) atoms. In the third Zn site, Zn(2) is bonded in a 12-coordinate geometry to three equivalent Co(1), three equivalent Zn(1), three equivalent Zn(2), and three equivalent Zn(3) atoms. is represented by the CIF card [CIF]
