Abstract: In the absence of conventional hydrogen bonding, the molecules of 4,6-di-O-acetyl-2-O-tosyl-myo-inositol 1,3,5-orthoformate, C₁₈H₂₀O₁₀S, (I), and 4,6-di-O-acetyl-2-O-tosyl-myo-inositol 1,3,5-orthobenzoate, C₂₄H₂₄O₁₀S, (II), are associated via C-HO interactions. Molecules of (II) are additionally linked via dipolar S=OC=O contacts. It is interesting to note that the sulfonyl O atom involved in the dipolar S=OC=O contacts does not take part in any other interaction, indicating the competitive nature of this contact relative to the weak hydrogen-bonding interactions.

Formula: C₁₈H₂₀O₁₀S and C₂₄H₂₄O₁₀S
