(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 of 1–3 are analyzed and compared with regard to their
