24. Super spacegroup I′2/m(0q0)s0 is a nonstandard setting of spacegroup C2/m(0q0)s0. We have chosen to use the nonstandard setting for consistency with our previous descriptions of Te-III (Ref. 15) and Se-IV (Ref. 16). In the C2/m(0q0)s0 setting the structural parameters of S-III at 100.5 GPa are a=2.808 Å, b=3.457 Å, c=2.210 Å, β=113.27°, with q=0.721.

26. Different models of preferred orientation have little effect on the variation in next-nearest-neighbor distance-all the models investigated resulted in a variation in the range 2.11(2)-2.42(3) Å at 100.5 GPa.
27. The equivalent primitive unit cell for S-IV at 63.7 GPa is a =2.284 Å, b=2.966 Å, c=5.508 Å, α=102.35°, β=92.91°, and γ=111.89°.
