The material structure described by Yb4Zn11 crystallizes in the tetragonal I4_1/amd space group. Yb(1) is bonded in a 1-coordinate geometry to one Zn(1), one 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 4-coordinate geometry to four equivalent Yb(1) atoms. In the second Zn site, Zn(2) is bonded in a distorted hexagonal planar geometry to two equivalent Yb(1) and four equivalent Zn(3) atoms. In the third Zn site, Zn(3) is bonded in a 9-coordinate geometry to three equivalent Yb(1), one Zn(2), and five equivalent Zn(3) atoms. is represented by the CIF card [CIF]
