The material structure described by Ce2Ni2Mg crystallizes in the tetragonal P4/mbm space group. Mg(1) is bonded in a distorted square co-planar geometry to four equivalent Ni(1) atoms. Ce(1) is bonded in a 6-coordinate geometry to six equivalent Ni(1) atoms. Ni(1) is bonded in a 9-coordinate geometry to two equivalent Mg(1), six equivalent Ce(1), and one Ni(1) atom. is represented by the CIF file [CIF]
