Materials Data on Ta by Materials Project
Ta crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. there are four inequivalent Ta sites. In the first Ta site, Ta is bonded in a 8-coordinate geometry to eight Ta atoms. There are four shorter (2.80 Å) and four longer (2.83 Å) Ta–Ta bond lengths. In the second Ta site, Ta is bonded in a 9-coordinate geometry to nine Ta atoms. There are a spread of Ta–Ta bond distances ranging from 2.93–3.02 Å. In the third Ta site, Ta is bonded in a 8-coordinate geometry to eight Ta atoms. There are a spread of Ta–Ta bond distances ranging from 2.72–2.99 Å. In the fourth Ta site, Ta is bonded in a 10-coordinate geometry to ten Ta atoms. There are one shorter (2.69 Å) and four longer (3.06 Å) Ta–Ta bond lengths.
