Materials Data on Ta4CoNi by Materials Project
Ta4CoNi is Khatyrkite-derived structured and crystallizes in the tetragonal I422 space group. The structure is three-dimensional. Ta is bonded in a 4-coordinate geometry to two equivalent Co and two equivalent Ni atoms. Both Ta–Co bond lengths are 2.63 Å. Both Ta–Ni bond lengths are 2.63 Å. Co is bonded in a distorted q6 geometry to eight equivalent Ta and two equivalent Ni atoms. Both Co–Ni bond lengths are 2.46 Å. Ni is bonded in a 10-coordinate geometry to eight equivalent Ta and two equivalent Co atoms.
