Materials Data on TmNiGe2 by Materials Project

Abstract

TmNiGe2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Tm is bonded in a 12-coordinate geometry to four equivalent Ni and ten Ge atoms. All Tm–Ni bond lengths are 3.12 Å. There are a spread of Tm–Ge bond distances ranging from 3.07–3.19 Å. Ni is bonded in a 9-coordinate geometry to four equivalent Tm and five Ge atoms. There are a spread of Ni–Ge bond distances ranging from 2.28–2.39 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to six equivalent Tm, one Ni, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.48 Å. In the second Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Tm and four equivalent Ni atoms.
