The structure described by Yb3Zn11 crystallizes in the orthorhombic Immm space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 12-coordinate geometry to four equivalent Zn(2), four equivalent Zn(4), and eight equivalent Zn(3) atoms. In the second Yb site, Yb(2) is bonded in a 16-coordinate geometry to two equivalent Zn(1), two equivalent Zn(2), six equivalent Zn(3), and six equivalent Zn(4) atoms. There are four inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to four equivalent Yb(2), four equivalent Zn(2), and four equivalent Zn(4) atoms to form distorted face-sharing ZnYb4Zn8 cuboctahedra. In the second Zn site, Zn(2) is bonded in a 12-coordinate geometry to two equivalent Yb(1), two equivalent Yb(2), two equivalent Zn(1), two equivalent Zn(3), and four equivalent Zn(4) atoms. In the third Zn site, Zn(3) is bonded in a 10-coordinate geometry to two equivalent Yb(1), three equivalent Yb(2), one Zn(2), one Zn(3), and three equivalent Zn(4) atoms. In the fourth Zn site, Zn(4) is bonded in a 10-coordinate geometry to one Yb(1), three equivalent Yb(2), one Zn(1), two equivalent Zn(2), and three equivalent Zn(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
