The material described by Yb(CoGe)2 crystallizes in the tetragonal I4/mmm space group. Yb(1) is bonded in a 16-coordinate geometry to eight equivalent Co(1) and eight equivalent Ge(1) atoms. Co(1) is bonded to four equivalent Yb(1) and four equivalent Ge(1) atoms to form a mixture of distorted edge, corner, and face-sharing CoYb4Ge4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Yb(1), four equivalent Co(1), and one Ge(1) atom. is represented by the CIF card [CIF]
