Materials Data on Li(TmGe2)2 by Materials Project

Li(TmGe2)2 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. Li is bonded in a 5-coordinate geometry to four equivalent Tm and five Ge atoms. There are two shorter (3.06 Å) and two longer (3.14 Å) Li–Tm bond lengths. There are a spread of Li–Ge bond distances ranging from 2.35–2.48 Å. There are two inequivalent Tm sites. In the first Tm site, Tm is bonded in a 10-coordinate geometry to ten Ge atoms. There are a spread of Tm–Ge bond distances ranging from 2.96–3.18 Å. In the second Tm site, Tm is bonded in a 4-coordinate geometry to four equivalent Li and ten Ge atoms. There are a spread of Tm–Ge bond distances ranging from 3.04–3.39 Å. There are four inequivalent Ge sites. In the first Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Li and four Tm atoms. In the second Ge site, Ge is bonded in a 2-coordinate geometry to two equivalent Li and four Tm atoms. In the third Ge site, Ge is bonded in a distorted single-bond geometry to one Li, six Tm, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.55 Å. In the fourth Ge site, Ge is bonded in a 8-coordinate geometry to six Tm and two equivalent Ge atoms.
