The superconducting <jats:italic>T<\/jats:italic><jats:sub>c<\/jats:sub> shows 30\u201370\u2009K in pressure range of 100\u2013170\u2009GPa (low-<jats:italic>T<\/jats:italic><jats:sub>c<\/jats:sub> phase) and increases to 203\u2009K, which sets a record for the highest <jats:italic>T<\/jats:italic><jats:sub>c<\/jats:sub> in all materials, for the samples annealed by heating it to room temperature at pressures above 150\u2009GPa (high-<jats:italic>T<\/jats:italic><jats:sub>c<\/jats:sub> phase). Here we present a solid H<jats:sub>5<\/jats:sub>S<jats:sub>2<\/jats:sub> phase predicted as the low-<jats:italic>T<\/jats:italic><jats:sub>c<\/jats:sub> phase by the application of the genetic algorithm technique for crystal structure searching and first-principles calculations to sulfur-hydrogen system under high-pressure. The H<jats:sub>5<\/jats:sub>S<jats:sub>2<\/jats:sub> phase is thermodynamically stabilized at 110\u2009GPa, in which asymmetric hydrogen bonds are formed between H<jats:sub>2<\/jats:sub>S and H<jats:sub>3<\/jats:sub>S molecules. Calculated <jats:italic>T<\/jats:italic><jats:sub>c<\/jats:sub> values show 50\u201370\u2009K in pressure range of 100\u2013150\u2009GPa within the harmonic approximation, which can reproduce the experimentally observed low-<jats:italic>T<\/jats:italic><jats:sub>c<\/jats:sub> phase.
