Materials Data on Yb(CoGe)2 by Materials Project
Yb(CoGe)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Yb is bonded in a 8-coordinate geometry to eight equivalent Co and eight equivalent Ge atoms. All Yb–Co bond lengths are 3.24 Å. All Yb–Ge bond lengths are 3.09 Å. Co is bonded to four equivalent Yb and four equivalent Ge atoms to form a mixture of distorted edge, corner, and face-sharing CoYb4Ge4 tetrahedra. All Co–Ge bond lengths are 2.33 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Yb, four equivalent Co, and one Ge atom. The Ge–Ge bond length is 2.66 Å.
