Lu6Zn23 crystallizes in the cubic Fm-3m space group. Lu(1) is bonded in a 12-coordinate geometry to four equivalent Zn(2), four equivalent Zn(3), and four equivalent Zn(4) atoms. There are four inequivalent Zn sites. In the first Zn site, Zn(4) is bonded in a 12-coordinate geometry to three equivalent Lu(1), three equivalent Zn(2), three equivalent Zn(3), and three equivalent Zn(4) atoms. In the second Zn site, Zn(1) is bonded in a body-centered cubic geometry to eight equivalent Zn(3) atoms. In the third Zn site, Zn(2) is bonded to four equivalent Lu(1), four equivalent Zn(3), and four equivalent Zn(4) atoms to form a mixture of corner and face-sharing ZnLu4Zn8 cuboctahedra. In the fourth Zn site, Zn(3) is bonded in a 13-coordinate geometry to three equivalent Lu(1), one Zn(1), three equivalent Zn(2), three equivalent Zn(3), and three equivalent Zn(4) atoms.
