The structure described by Mg2Ni is Khatyrkite structured and crystallizes in the tetragonal I4/mcm space group. Mg(1) is bonded in a 4-coordinate geometry to four equivalent Ni(1) atoms. Ni(1) is bonded in a 8-coordinate geometry to eight equivalent Mg(1) atoms. is represented by the CIF file [CIF]
