Enclave inclusion of nitromethane by a new crown host. X-Ray crystal structure of the inclusion complex and host selectivity properties
Abstract
A 21-membered macroring (1) incorporating as characteristic building blocks a 2,6-bridged pyridino site and three adjacent catechol moieties is shown to form selectively an inclusion complex with nitromethane, the crystal structure of which demonstrates a completely encapsulated guest molecule.
