Materials Data on Yb2CdGe2 by Materials Project
Yb2CdGe2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Yb is bonded in a 6-coordinate geometry to four equivalent Cd and six equivalent Ge atoms. All Yb–Cd bond lengths are 3.49 Å. There are two shorter (3.04 Å) and four longer (3.11 Å) Yb–Ge bond lengths. Cd is bonded to eight equivalent Yb and four equivalent Ge atoms to form a mixture of distorted corner and face-sharing CdYb8Ge4 cuboctahedra. All Cd–Ge bond lengths are 2.91 Å. Ge is bonded in a 9-coordinate geometry to six equivalent Yb, two equivalent Cd, and one Ge atom. The Ge–Ge bond length is 2.57 Å.
