The material structure described by MgTb2S4 crystallizes in the tetragonal I-42d space group. Mg(1) is bonded in a 4-coordinate geometry to eight equivalent S(1) atoms. Tb(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 Tb(1) atoms. is represented by the CIF card [CIF]
