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. The compound has no particular application, unlike the related sulfur compound
disulfur dichloride.
The molecular structure is akin to that of
disulfur dichloride (S
2Cl
2). According to
electron diffraction measurements, the BrSSBr dihedral angle is 84° and the Br-S-S angle is 107°. The S-S distance is 1.980 Å, ca. 0.050 Å shorter than for S
2Cl
2.
