The structure of the 1:3 complex between 5,5′ -biscalix[4]arene-hexabenzoate and toluene has been determined by a single crystal X-ray diffraction study. The two calix[4]arene subunits of the 5,5′-biscalix[4]arene system are related by an inversion center and are joined by an eclipsed biphenyl para-para linkage. Each calix[4]arene moiety displays a 1,3-alternate conformation and includes a toluene molecule within two opposite benzoate groups, while a third toluene molecule lies close to a crystallographic inversion center.

Abstract
The structure of the 1:3 complex between 5,5′ -biscalix[4]arene-hexabenzoate and toluene has been determined by a single crystal X-ray diffraction study. The two calix[4]arene subunits of the 5,5′-biscalix[4]arene system are related by an inversion center and are joined by an eclipsed biphenyl para-para linkage. Each calix[4]arene moiety displays a 1,3-alternate conformation and includes a toluene molecule within two opposite benzoate groups, while a third toluene molecule lies close to a crystallographic inversion center.File in questo prodotto:
