Materials Data on Ta5Si3 by Materials Project
Ta5Si3 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 Si atoms. There are a spread of Ta–Si bond distances ranging from 2.65–2.94 Å. In the second Ta site, Ta is bonded in a 6-coordinate geometry to two equivalent Ta and four equivalent Si atoms. Both Ta–Ta bond lengths are 2.55 Å. All Ta–Si bond lengths are 2.67 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 10-coordinate geometry to ten Ta atoms. In the second Si site, Si is bonded in a 10-coordinate geometry to eight equivalent Ta and two equivalent Si atoms. Both Si–Si bond lengths are 2.55 Å.
