Beschreibungen/Notizen

• During the investigation of the Ga 3+ –HCl–cucurbituril system, we prepared crystals of the title compound, tetrakis(hydroxonium) bis(tetrachlorogallate) dichloride cucurbituril decahydrate, by slow evaporation of an aqueous hydrochloric solution containing Ga 3+ and cucurbituril at room temperature in air. The compound appeared to be isostructural with the cucurbituril tetrachloroferrate(III) adduct. The structure contains H 7 O 3 + cations, [GaCl 4 ] − anions, cucurbituril and water molecules. The centres of the cucurbituril molecules are arranged as body-centered packing and [GaCl 4 ] − anions are situated in space between them. There is a complicated network of hydrogen bonds in the structure.
