The material structure described by MgYb2S4 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. Yb(1) is bonded to eight equivalent S(1) atoms to form a mixture of distorted corner, edge, and face-sharing YbS8 hexagonal bipyramids. S(1) is bonded in a 5-coordinate geometry to one Mg(1) and four equivalent Yb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
