Abstract

TaVCo is Frank-Kasper $$\mu$$ Phase-derived structured and crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are eight inequivalent Ta sites. In the first Ta site, Ta is bonded in a 12-coordinate geometry to four Ta, five V, and seven Co atoms. There are a spread of Ta–Ta bond distances ranging from 2.94–3.01 Å. There are a spread of Ta–V bond distances ranging from 2.88–2.93 Å. There are three shorter (2.78 Å) and four longer (2.89 Å) Ta–Co bond lengths. In the second Ta site, Ta is bonded in a 12-coordinate geometry to four Ta, seven V, and five Co atoms. There are two shorter (3.01 Å) and one longer (3.12 Å) Ta–Ta bond lengths. There are a spread of Ta–V bond distances ranging from 2.86–2.93 Å. There are a spread of Ta–Co bond distances ranging from 2.83–2.87 Å.
