Abstract: The structure of the title acid as the monohydrate, C₁₄H₁₈O₁₁·H₂O, displays hydrogen bonding which connects the molecules in layers parallel to (10 $\overline{1}$ ). In the anhydrous glucopyranose, C₁₄H₂₀O₁₀, only chain connectivity is attained but, due to disorder of the OH group, only partially and in two modes, one less favoured than the other. This provides incomplete connectivity between molecules in corrugated layers parallel to (010).

Formula: C₁₄H₁₈O₁₁·H₂O and C₁₄H₂₀O₁₀
