Hydronium perchlorate–dibenzo-18-crown-6 (1/1): monoclinic polymorph
The asymmetric unit of the title compound, H(3)O(+)·ClO(4) (−)·C(20)H(24)O(6), contains two molecules/ions of each species. Both dibenzo-18-crown-6 molecules have a complexed hydronium ion inside their cavity with O—H⋯O and O—H⋯(O,O) links between the two species. The associated perchlorate anion...

| Sumario: | The asymmetric unit of the title compound, H(3)O(+)·ClO(4) (−)·C(20)H(24)O(6), contains two molecules/ions of each species. Both dibenzo-18-crown-6 molecules have a complexed hydronium ion inside their cavity with O—H⋯O and O—H⋯(O,O) links between the two species. The associated perchlorate anions also accept O—H⋯O hydrogen bonds from the hydronium ion. Both crown ether molecules are present in a butterfly conformation with approximate C (2v) symmetry and their cavities are closed by the benzene ring of a neighbouring molecule. The packing is consolidated by C—H⋯O and C—H⋯π interactions. |
