Metal complex, and adsorbent material, storage material and separation material comprising metal complex

摘要

The metal complex comprises a multivalent carboxylic acid compound, at least one metal ion selected from ions of metals belonging to Groups 2 to 13 of the periodic table, an organic ligand capable of multidentate binding to the metal ion, and a C1 or C2 monocarboxylic acid compound. The metal complex has excellent gas adsorption, storage, and separation performance as well as excellent durability. The metal complex is stably present under high temperature and high humidity, and can maintain high adsorption performance.
