Li4Yb5Ge4 crystallizes in the tetragonal I4/m space group. Li(1) is bonded in a 3-coordinate geometry to three equivalent Ge(1) atoms. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. In the second Yb site, Yb(2) is bonded in a square co-planar geometry to four equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to three equivalent Li(1), one Yb(2), and five equivalent Yb(1) atoms.
Li4Yb5Ge4 crystallizes in the tetragonal I4/m space group. Li(1) is bonded in a 3-coordinate geometry to three equivalent Ge(1) atoms. There are two shorter (2.70 Å) and one longer (2.86 Å) Li(1)-Ge(1) bond length. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. There are a spread of Yb(1)-Ge(1) bond distances ranging from 3.09-3.15 Å. In the second Yb site, Yb(2) is bonded in a square co-planar geometry to four equivalent Ge(1) atoms. All Yb(2)-Ge(1) bond lengths are 3.17 Å. Ge(1) is bonded in a 9-coordinate geometry to three equivalent Li(1), one Yb(2), and five equivalent Yb(1) atoms.
