The host-guest complex between cone-25,26:27,28-bis(methylenedioxy)calix[4]arene and dichloromethane

The title compound, 25,26: 27,28-bis( methylenedioxy) pentacyclo[ 19.3.1.1(3,7).1(9,13).1(15,19)] octacosa-1(25) 3,5,7(28), 9,11,13(27),15,17,19( 26), 21,23-dodecaene dichloromethane solvate, C30H24O4.CH2Cl2, possesses crystallographic twofold symmetry in both components. The calixarene shows a pinched cone conformation with an elliptical cavity, in which the guest dichloromethane solvent molecule is accommodated. The contact distance between guest and host (H... ring centroid = 2.44 Angstrom) is extremely short.
