Materials Data on Ta2Al by Materials Project
Ta2Al is beta Plutonium-derived structured and crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. there are three inequivalent Ta sites. In the first Ta site, Ta is bonded in a 11-coordinate geometry to nine Ta and five Al atoms. There are a spread of Ta–Ta bond distances ranging from 2.69–3.30 Å. There are a spread of Ta–Al bond distances ranging from 2.97–3.13 Å. In the second Ta site, Ta is bonded in a 12-coordinate geometry to seven Ta and five Al atoms. There are one shorter (2.82 Å) and two longer (3.19 Å) Ta–Ta bond lengths. There are a spread of Ta–Al bond distances ranging from 2.68–2.90 Å. In the third Ta site, Ta is bonded in a 2-coordinate geometry to eleven Ta and four Al atoms. The Ta–Ta bond length is 2.72 Å. There are two shorter (2.72 Å) and two longer (3.03 Å) Ta–Al bond lengths. There are two inequivalent Al sites. In the first Al site, Al is bonded in a 10-coordinate geometry to nine Ta and one Al atom. The Al–Al bond length is 2.79 Å. In the second Al site, Al is bonded to twelve Ta atoms to form edge-sharing AlTa12 cuboctahedra.
