The crystal structure described by Ni2Ta is Titanium Disilicide-like structured and crystallizes in the tetragonal I4/mmm space group. Ta(1) is bonded in a distorted q6 geometry to ten equivalent Ni(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to five equivalent Ta(1) and five equivalent Ni(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
