Abstract

Co3Ta crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. there are three inequivalent Ta sites. In the first Ta site, Ta is bonded in a 6-coordinate geometry to fifteen Co atoms. There are a spread of Ta–Co bond distances ranging from 2.64–2.83 Å. In the second Ta site, Ta is bonded in a 12-coordinate geometry to three equivalent Ta and twelve Co atoms. All Ta–Ta bond lengths are 2.99 Å. There are a spread of Ta–Co bond distances ranging from 2.73–2.79 Å. In the third Ta site, Ta is bonded in a 10-coordinate geometry to three equivalent Ta and thirteen Co atoms. There are a spread of Ta–Co bond distances ranging from 2.64–2.96 Å. There are five inequivalent Co sites. In the first Co site, Co is bonded to three equivalent Ta and nine Co atoms to form distorted CoTa3Co9 cuboctahedra that share corners with twelve CoTa4Co8 cuboctahedra, edges with six equivalent CoTa3Co9 cuboctahedra, and faces with twenty CoTa6Co6 cuboctahedra. There are a spread of Co–Co bond distances ranging from 2.35–2.75 Å. In the second Co site, Co is bonded to six Ta and six Co atoms to form CoTa6Co6 cuboctahedra that share corners with twelve CoTa4Co8more »« less
