| Popis: | In the title compound, C51H58O10·C4H8Br2, both the host and guest are completed by crystallographic twofold symmetry (one carbon atom of the host lies on the rotation axis). The pentagonal-shaped macrocycle has a pair of buteneoxy substituents on one of its faces and one molecule of 1,4-dibromobutane is encapsulated within the cavity of the pillararene, forming a 1:1 inclusion complex. The terminal alkene parts, which project outwards from the pillararene ring, exhibit positional disorder over two sets of sites in a 0.52 (2): 0.48 (2) ratio. The host and guest interact via C—H...O, C—H...Br and C—H...π interactions and adjacent host molecules interact via C—H...O and C—H...π bonds. |
