Two metal–organic frameworks containing barium were synthesized hydrothermally and investigated for their catalytic properties. Ba2F2[O3SC2H4SO3] has barium fluoride layers linked by organic 1,2-ethanedisulfonate molecules. Ba[O3SC2H4SO3] has discrete barium centers arranged in layers and connected covalently by ethanedisulfonate bridges. Thermogravimetric analysis showed that Ba2F2[O3SC2H4SO3] is stable to ca. 325 °C and Ba[O3SC2H4SO3] to ca. 375 °C. These materials expand the metal–organic frameworks available for group II metals bound to organodisulfonate linkers and are potentially useful for a range of heterogeneous acid catalysis reactions.
