Materials Data on Ta5Ga3 by Materials Project

Ta5Ga3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Ta sites. In the first Ta site, Ta is bonded in a 8-coordinate geometry to two equivalent Ta and six equivalent Ga atoms. Both Ta–Ta bond lengths are 2.64 Å. All Ta–Ga bond lengths are 2.72 Å. In the second Ta site, Ta is bonded in a 5-coordinate geometry to five equivalent Ga atoms. There are a spread of Ta–Ga bond distances ranging from 2.67–2.88 Å. Ga is bonded in a 9-coordinate geometry to nine Ta atoms.
