Odd-membered higher heterocalixarene architecture featuring cage conformation. Synthesis and X-ray structure analysis of a 1:2:2 inclusion cascade complex with acetone and dichloromethane

Abstract

The first crystal structure of a heterocalix[9]arene host molecule created from six benzimidazol-2-one and three p-methylanisole units displays guest binding via a cascade of interactions of the two acetone and two dichloromethane guest molecules with the host and with each other as well.
