The crystal structure described by MgEu2S4 crystallizes in the tetragonal I-42d space group. Mg(1) is bonded in a distorted square co-planar geometry to four equivalent S(1) atoms. Eu(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. S(1) is bonded in a 5-coordinate geometry to one Mg(1) and four equivalent Eu(1) atoms. is represented by the CIF card [CIF]
