This article reports a cheap and high yield (85%) route for synthesis of 3H-1,2-benzodithiol-3-thione (btt). Treatment of benzisothiazolinone (Hbit) with P₄S₁₀ yielded a mixture of two products which are (btt) and thiobenzisothiazolinone (Htbit). This mixture was characterized and confirmed using FT-IR, ¹H-,¹³C- NMR, (COSY, HSQC)-2D-NMR and GC-MS. The optimal conditions for synthesis of btt in high yield and purity were investigated. The pure btt was characterized using FTIR, ¹H-NMR, GC-MS, elemental analyses and thermal analyses (TG, DTG, DTA and DSC). Furthermore, the pure btt was examined for its ability in store of hydrogen and the result shows that btt is able to store 0.4611 wt% H₂ under 90 bar at 77 K giving equilibrium pressure equal to 0.460 wt% H₂.
