Single crystal X-ray diffraction analyses of calixarene-bis-crown-6 (1) and calixarene-bis-benzocrown-6⋯1,2-dichloroethane (2) are reported. Thesestructures offer an opportunity to study the conformation of calixarene-bis-crown-6 molecules in the absence of solvent, and when very weakly solvated. These structures exhibit different conformations of the crown ring, and limited flexibility of the calixarene,but do not show solvent or crown inclusion in the calixarene cavity. Comparisons to similar structures are made, and the implications for cesium binding are discussed.
