Materials Data on Tm3(GePd)4 by Materials Project

Abstract

Tm3(PdGe)4 crystallizes in the orthorhombic Immm 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 Pd and six Ge atoms. There are four shorter (3.04 Å) and two longer (3.12 Å) Tm–Pd bond lengths. There are two shorter (3.00 Å) and four longer (3.02 Å) Tm–Ge bond lengths. In the second Tm site, Tm is bonded to six Ge atoms to form distorted edge-sharing TmGe6 octahedra. All Tm–Ge bond lengths are 3.03 Å. Pd is bonded in a 12-coordinate geometry to three equivalent Tm and four Ge atoms. There are one shorter (2.55 Å) and three longer (2.59 Å) Pd–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to six Tm, two equivalent Pd, and one Ge atom. The Ge–Ge bond length is 2.67 Å. In the second Ge site, Ge is bonded in a 9-coordinate geometry to three Tm and six equivalent Pd atoms.
