Abstract
NiAlTa crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are four inequivalent Ta sites. In the first Ta site, Ta is bonded in a 12-coordinate geometry to four Ta, five Ni, and seven Al atoms. There are a spread of Ta–Ta bond distances ranging from 2.96–3.18 Å. There are three shorter (2.77 Å) and two longer (2.97 Å) Ta–Ni bond lengths. There are a spread of Ta–Al bond distances ranging from 2.89–2.97 Å. In the second Ta site, Ta is bonded in a 12-coordinate geometry to four Ta, seven Ni, and five Al atoms. There are one shorter (2.87 Å) and two longer (3.05 Å) Ta–Ta bond lengths. There are a spread of Ta–Ni bond distances ranging from 2.82–2.95 Å. There are a spread of Ta–Al bond distances ranging from 2.83–2.93 Å. In the third Ta site, Ta is bonded in a 12-coordinate geometry to four Ta, five Ni, and seven Al atoms. The Ta–Ta bond length is 3.18 Å. There are three shorter (2.77 Å) and two longer (2.97 Å) Ta–Ni bond lengths. There are a spread of Ta–Al bond distances ranging from 2.89–2.97 Å. In the fourth Ta site, Ta is bonded in amore »
