Weak but important: The chloride anion binding properties of diametrically strapped calixpyrroles bearing benzene (see structure), pyrrole, and furan moieties in the strap have been studied in the solid state, in solution, and through theoretical analyses. The results obtained provide support for the notion that C[BOND]H⋅⋅⋅Cl hydrogen bonds are significant and contribute substantially to the Cl binding energetics.
