The material structure described by HoZn12 crystallizes in the tetragonal I4/mmm space group. Ho(1) is bonded in a 20-coordinate geometry to four equivalent Zn(2), eight equivalent Zn(1), and eight equivalent Zn(3) atoms. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to two equivalent Ho(1), two equivalent Zn(1), four equivalent Zn(2), and four equivalent Zn(3) atoms to form a mixture of face, corner, and edge-sharing ZnHo2Zn10 cuboctahedra. In the second Zn site, Zn(3) is bonded in a distorted q6 geometry to two equivalent Ho(1), two equivalent Zn(3), four equivalent Zn(1), and four equivalent Zn(2) atoms. In the third Zn site, Zn(2) is bonded in a 10-coordinate geometry to one Ho(1), one Zn(2), four equivalent Zn(1), and four equivalent Zn(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
