The structures of 1,2-bis(o-nitrophenoxy)benzene [(1), C18H12N2O6], 2,2′-o-phenylenedioxybis(phenylamine) [(2), C18H16N2O2], and meso- 2,2′-o-phenylenedioxybis(cyclohexanol) [(3), C18H26O4], potential precursors for rigid crown ether molecules, are presented. Each structure displays hydrogen bonding. Compound (1) exhibits weak C—H...O interactions, while (2) and (3) display extensive E—H...E and E—H...π (E = N, O) bonding.
