Materials Data on LiTmGe by Materials Project
LiTmGe crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Li is bonded to four Ge atoms to form a mixture of distorted corner and edge-sharing LiGe4 tetrahedra. There are two shorter (2.68 Å) and two longer (2.73 Å) Li–Ge bond lengths. Tm is bonded in a 5-coordinate geometry to five Ge atoms. There are one shorter (2.94 Å) and four longer (2.97 Å) Tm–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to six equivalent Li and three equivalent Tm atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to three equivalent Li and six equivalent Tm atoms.
