Materials Data on Tb2In3Cu by Materials Project

Abstract

Tb2CuIn3 is Tungsten boride-derived structured and crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 12-coordinate geometry to three equivalent Cu and nine In atoms. All Tb–Cu bond lengths are 3.06 Å. There are a spread of Tb–In bond distances ranging from 3.14–3.67 Å. In the second Tb site, Tb is bonded in a 9-coordinate geometry to three equivalent Cu and nine In atoms. All Tb–Cu bond lengths are 3.43 Å. There are a spread of Tb–In bond distances ranging from 3.15–3.69 Å. Cu is bonded in a 10-coordinate geometry to six Tb and four In atoms. There are three shorter (2.76 Å) and one longer (2.94 Å) Cu–In bond lengths. There are three inequivalent In sites. In the first In site, In is bonded in a 10-coordinate geometry to six Tb, three equivalent Cu, and one In atom. The In–In bond length is 3.24 Å. In the second In site, In is bonded in a 10-coordinate geometry to six Tb and four In atoms. All In–In bond lengths are 2.87 Å. In the third In site, In is bonded in a 10-coordinate geometry to six Tb, one Cu, and three equivalent In atoms.
