Materials Data on TmCoGe2 by Materials Project

Abstract

TmCoGe2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Tm is bonded in a 8-coordinate geometry to four equivalent Co and ten Ge atoms. All Tm–Co bond lengths are 3.16 Å. There are a spread of Tm–Ge bond distances ranging from 3.01–3.20 Å. Co is bonded in a 5-coordinate geometry to four equivalent Tm and five Ge atoms. There are a spread of Co–Ge bond distances ranging from 2.25–2.37 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 Co, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.53 Å. In the second Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Tm and four equivalent Co atoms.
