Yb(ZnGe)2 crystallizes in the tetragonal I4/mmm space group. Yb(1) is bonded in a 16-coordinate geometry to eight equivalent Zn(1) and eight equivalent Ge(1) atoms. Zn(1) is bonded to four equivalent Yb(1) and four equivalent Ge(1) atoms to form a mixture of distorted face, corner, and edge-sharing ZnYb4Ge4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Yb(1), four equivalent Zn(1), and one Ge(1) atom.
