THE SOLID-STATE INCLUSION COMPLEX BETWEEN THE MONO-ANION OF CALIX[4]ARENE AND PROTONATED DIAMINO-BICYCLOUNDECANE

Abstract

Diamino-bicycloundecane mono-deprotonates H-calix[4]arene and the solid-structure of the resulting salt has been determined by X-ray crystallography. Two different complexes are present in the structure with the Diamino-bicycloundecane cation held in the calix[4]arene cavity by CH-p interactions. In the packing there is a hydrogen-bonded polymeric chain. Both the complexes formed layered structures with differing inter-layer distances.
