The material structure described by MgCe2Se4 crystallizes in the tetragonal I-42d space group. Mg(1) is bonded in a distorted square co-planar geometry to four equivalent Se(1) atoms. Ce(1) is bonded in a 8-coordinate geometry to eight equivalent Se(1) atoms. Se(1) is bonded in a 5-coordinate geometry to one Mg(1) and four equivalent Ce(1) atoms. is represented by the CIF file [CIF]
