The material described by Ta2Ni is Khatyrkite structured and crystallizes in the tetragonal I4/mcm space group. Ta(1) is bonded in a 4-coordinate geometry to four equivalent Ni(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to eight equivalent Ta(1) and two equivalent Ni(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
