Three tartaric ester and tartaric acid derivatives (1–3) with the hydroxy groups being linked via cyclic acetal (1,3-dioxolane) formation to a rigid core, containing phenyl and ethynyl units, have been synthesized. Their crystal structures are reported, emphasizing the molecular geometry, intermolecular interactions, and the resulting packing motifs. All dioxolane rings present in the crystal structures...
Considering the specific supramolecular synthon design of carboxylic acid and alcoholic hydroxyl groups in the field of crystal engineering, we compared the solid state structures of particular benzoates and corresponding acids 1–4 both in the non-spacered (1, 2) and spacered (3, 4) forms. Based on the single crystal X-ray study, there is only a slight influence of the phenylacetylene spacer with...
