Materials Data on TmGe2 by Materials Project

TmGe2 is Zirconium Disilicide structured and crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Tm is bonded in a 10-coordinate geometry to ten Ge atoms. There are a spread of Tm–Ge bond distances ranging from 2.91–3.20 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 4-coordinate geometry to six equivalent Tm and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.59 Å. In the second Ge site, Ge is bonded in a 8-coordinate geometry to four equivalent Tm and four equivalent Ge atoms. All Ge–Ge bond lengths are 2.81 Å.
