Title: Materials Data on Tm2CuGe6 by Materials Project

Abstract

Tm2CuGe6 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. 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 2.95–3.09 Å. In the second Tm site, Tm is bonded in a 8-coordinate geometry to four equivalent Cu and ten Ge atoms. All Tm–Cu bond lengths are 3.07 Å. There are a spread of Tm–Ge bond distances ranging from 3.08–3.37 Å. Cu is bonded in a 9-coordinate geometry to four equivalent Tm and five Ge atoms. There are a spread of Cu–Ge bond distances ranging from 2.30–2.41 Å. There are six inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Tm, two equivalent Cu, and five Ge atoms. There are one shorter (2.49 Å) and four longer (2.85 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a 7-coordinate geometry to two equivalent Tm and five Ge atoms. All Ge–Ge bond lengths are 2.85 Å. In the third Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Tm, two equivalentmore » Cu, and five Ge atoms. The Ge–Ge bond length is 2.51 Å. In the fourth Ge site, Ge is bonded in a 7-coordinate geometry to two equivalent Tm and five Ge atoms. In the fifth Ge site, Ge is bonded in a 1-coordinate geometry to six Tm, one Cu, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.53 Å. In the sixth Ge site, Ge is bonded in a 8-coordinate geometry to six Tm and two equivalent Ge atoms.« less
