The compound described by YbCo4Ge2 crystallizes in the tetragonal P4_2/mnm space group. Yb(1) is bonded to six equivalent Ge(1) atoms to form a mixture of distorted edge and corner-sharing YbGe6 octahedra. The corner-sharing octahedral tilt angles are 39°. Co(1) is bonded in a 3-coordinate geometry to three equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to three equivalent Yb(1) and six equivalent Co(1) atoms. is represented by the CIF card [CIF]
