Benzene-1,3,5-triyl tris­(methane­sulfonate)

In the mol­ecule of the title compound, C9H12O9S3, the two methanesulfonate groups re located one above and one below the ring plane. The C—O—S angle range is 119.3 (2)–121.1 (2)°. This conformation is different from that of the benzene analog 1,2,5-tris­(p-toluene­sulfonate), which is a three-legged `table' with all fragments of the p-toluene­sulfonate on top of the benzene ring. In the crystal, the supra­molecular aggregation is completed by the presence of C—H⋯O hydrogen bonds.
