Abstract

TaVNi crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are seven inequivalent Ta sites. In the first Ta site, Ta is bonded in a 12-coordinate geometry to four Ta, five V, and seven Ni atoms. There are a spread of Ta–Ta bond distances ranging from 2.97–3.03 Å. There are a spread of Ta–V bond distances ranging from 2.86–2.92 Å. There are a spread of Ta–Ni bond distances ranging from 2.78–2.98 Å. In the second Ta site, Ta is bonded in a 12-coordinate geometry to four Ta, seven V, and five Ni atoms. The Ta–Ta bond length is 3.12 Å. There are a spread of Ta–V bond distances ranging from 2.88–2.96 Å. There are a spread of Ta–Ni bond distances ranging from 2.80–2.95 Å.
