Tetra­butyl­ammonium meso-octa­methyl­calix­[4]­pyrrole fluoride di­chloro­methane solvate

The title compound, C₁₆H₃₆N⁺·C₂₈H₃₆N₄·F⁻·CH₂Cl₂, is a calix­[4]­pyrrole macrocycle acting as a fluoride receptor by means of hydrogen bonding. Geometric comparisons with the previously published non-isostructural chloride-bound analogue are presented.
