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.
MgY2S4 crystallizes in the tetragonal I-42d space group. Mg(1) is bonded in a 4-coordinate geometry to eight equivalent S(1) atoms. There are four shorter (2.61 Å) and four longer (3.16 Å) Mg(1)-S(1) bond lengths. Y(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. There are a spread of Y(1)-S(1) bond distances ranging from 2.70-3.13 Å. S(1) is bonded in a 6-coordinate geometry to two equivalent Mg(1) and four equivalent Y(1) atoms.
