RESUMEN
In the title compound, C(10)H(20)O(4), the dioxane ring adopts a chair conformation. The tert-butyl group occupies an equatorial position, and is staggered with respect to the O atoms of the dioxane ring. In the crystal, mol-ecules are connected by O-Hâ¯O hydrogen-bonds into zigzag chains of R(4) (4)(8) and R(2) (2)(12) ring motifs that run parallel to the a axis.
RESUMEN
In the mol-ecule of the title compound, C(9)H(12)O(9)S(3), the two methanesulfonate groups re located one above and one below the ring plane. The C-O-S angle range is 119.3â (2)-121.1â (2)°. This conformation is different from that of the benzene analog 1,2,5-tris-(p-toluene-sulfonate), which is a three-legged 'table' with all fragments of the p-toluene-sulfonate on top of the benzene ring. In the crystal, the supra-molecular aggregation is completed by the presence of C-Hâ¯O hydrogen bonds.
