The material structure described by MgY2S4 crystallizes in the tetragonal I-42d space group. Mg(1) is bonded in a 4-coordinate geometry to eight equivalent S(1) atoms. Y(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. S(1) is bonded in a 6-coordinate geometry to two equivalent Mg(1) and four equivalent Y(1) atoms. is represented by the CIF file [CIF]
