In this study, we synthesize (H2S)2H2 by combining S and H2 directly in controlled ratios within diamond-anvil cells (DACs). On compression at 300 K, we observe the phase sequence I-II-II -III, where phase II is previously unreported. We map out the solid phases of (H2S)2H2 from 15 to 300 K, up to 185 GPa.
