Disulfur dibromide is the inorganic compound with the formula S
2Br
2. It is a yellow-brown liquid that fumes in air. It is prepared by direct combination of the elements and purified by vacuum distillation.[1] The compound has no particular application, unlike the related sulfur compound disulfur dichloride.
The molecular structure is Br–S–S–Br, akin to that of disulfur dichloride (S
2Cl
2). According to electron diffraction measurements, the angle between the Bra
–S–S and S–S–Brb
planes is 84° and the Br–S–S angle is 107°. The S–S distance is 198.0 pm, circa 5.0 pm shorter than for S
2Cl
2.[2]
