Materials Data on Ta5Ga3 by Materials Project

Abstract

Ta5Ga3 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. there are two inequivalent Ta sites. In the first Ta site, Ta is bonded in a 6-coordinate geometry to six Ga atoms. There are a spread of Ta–Ga bond distances ranging from 2.72–2.97 Å. In the second Ta site, Ta is bonded in a 6-coordinate geometry to two equivalent Ta and four equivalent Ga atoms. Both Ta–Ta bond lengths are 2.58 Å. All Ta–Ga bond lengths are 2.73 Å. There are two inequivalent Ga sites. In the first Ga site, Ga is bonded in a 10-coordinate geometry to ten Ta atoms. In the second Ga site, Ga is bonded in a 10-coordinate geometry to eight equivalent Ta and two equivalent Ga atoms. Both Ga–Ga bond lengths are 2.58 Å.
