Materials Data on TmZnGe by Materials Project

Abstract

TmZnGe crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Tm sites. In the first Tm site, Tm is bonded in a 12-coordinate geometry to six equivalent Zn and six equivalent Ge atoms. All Tm–Zn bond lengths are 2.88 Å. All Tm–Ge bond lengths are 3.23 Å. In the second Tm site, Tm is bonded to six equivalent Ge atoms to form distorted edge-sharing TmGe6 octahedra. All Tm–Ge bond lengths are 2.97 Å. Zn is bonded in a 6-coordinate geometry to three equivalent Tm and three equivalent Ge atoms. All Zn–Ge bond lengths are 2.51 Å. Ge is bonded in a 6-coordinate geometry to six Tm and three equivalent Zn atoms.
