Different interaction motifs of dipolar S=O...C=O contacts that associate diastereomers of 2,4(6)-di-O-benzoyl-6(4)-O-{[(1S)-7,7-dimethyl-2-oxobicyclo[2.2.1]heptan-1-ylmethyl]sulfonyl}-myo-inositol 1,3,5-orthoacetate.
Diastereomeric mixtures of 2,4(6)-di-O-benzoyl-6(4)-O-[(1S)-10-camphorsulfonyl]-myo-inositol 1,3,5-orthoesters associate in their crystal structures via different geometries of S=O...C=O short contacts, depending upon the substitution. A comparison of the dimeric association in the orthoacetate and orthoformate (solvated) derivatives shows a sheared parallel motif of dipolar S=O...C=O contacts bridging the former, whereas perpendicular S=O...C=O contacts occur in the latter. The title compound, C(32)H(34)O(11)S, is chiral, owing to the presence of the camphor moiety.
