The molecular structure is akin to that of hydrogen peroxide (H2O2). Disulfur dibromide is the most stable sulfur bromide, however, its thermal stability is low. It is a toxic, orange/yellow liquid that smokes in air due to the reaction with water vapor. In the presence of moisture, disulfur dibromide reacts violently with oxidants, releasing bromide anion and sulfur oxides. In general, its reactivity resembles that of S2Cl2. {{Sulfur compounds}} 2 : Sulfur halides|Bromides |
