Distances of centroids of phenyl rings between the p-tolyl group of the axis molecule and the catechol moiety of the crown ether were 398.779(2) Å at 30°C and 4.692(10) Å at 128°C. The degree between the phenyl rings was 7.9(2)° at 30°C and 45.0(6)° at 128°C. CCDC-631742-631743 contain the supplementary crystallographic data for this paper.
