The material described by Ta4CoNi is Khatyrkite-derived structured and crystallizes in the tetragonal I422 space group. Ta(1) is bonded in a 4-coordinate geometry to two equivalent Co(1) and two equivalent Ni(1) atoms. Co(1) is bonded in a 10-coordinate geometry to eight equivalent Ta(1) and two equivalent Ni(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to eight equivalent Ta(1) and two equivalent Co(1) atoms. is represented by the CIF file [CIF]
