By using quantum mechanical DFT calculations, the most probable structures of the bambus[6]uril.Cl-, bambus[6]uril.Br-, and bambus[6]uril.I- anionic complex species were derived. In these three complexes, each of the considered univalent halide anions, included in the center of the macrocyclic cavity, is bound by 12 weak C–H_X- (X- = Cl-, Br-, I-) hydrogen bonds between methine hydrogen atoms on the convex face of the glycoluril units and the respective anion. The lengths of the C–H_X- hydrogen bonds increase in the order Cl-/Br-/I-.
