The material structure described by Ce(Ni2Sn)2 crystallizes in the tetragonal I4/mcm space group. Ce(1) is bonded in a 8-coordinate geometry to eight equivalent Ni(1) and eight equivalent Sn(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to two equivalent Ce(1), four equivalent Ni(1), and four equivalent Sn(1) atoms. Sn(1) is bonded in a 12-coordinate geometry to four equivalent Ce(1) and eight equivalent Ni(1) atoms. is represented by the CIF file [CIF]
