Hybrid coordination polymers have been researching to architect 3D porous materials, robust structures thermally, and new secondary building blocks based on ‘crystal engineering’ and ‘supramolecular engineering’. Attempts to synthesize newly designed materials with various atoms on the periodic table, secondary building unit, flexibility or rigidity of organic linkers, pH and temperature control, and the addition of alkali metals have been led to extensive research. 5-sulfoisophthalate (SIPA), related to trimesate (TMA) has not been extensively investigated, but may yield interesting new architectures. To our knowledge, only a few structures have been characterized to date. Here, we report two structures containing a novel nickel fluoride cluster with four carboxylate groups in a roughly square arrangement: Ni2(TMA)(F)(H2O)42H2O and Ni2(SIPA)(F)(H2O)54H2O. Although fluoride is a common mineralizer for zeolite, metal phosphate, and metal phosphonate synthesis, it is not commonly used in the synthesis of carboxylate-based hybrid materials. The Férey group recently reported an iron pyromellitate and porous vanadocarboxylate incorporating framework F-. However, we are not aware of any other examples of hybrid systems containing fluoride. |
