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.
Disclosed is a method for producing a metal complex comprising a multivalent carboxylic acid compound, at least one metal ion, an organic ligand capable of multidentate binding to the metal ion, and a monocarboxylic acid compound, wherein the metal ion is used in the form of a metal salt having a counter anion of the metal ion, a conjugate acid of the counter anion having a first dissociation exponent larger by 0 to 6 than that of the multivalent carboxylic acid compound, and at least one of the multivalent carboxylic acid compound, the metal ion, the organic ligand capable of multidentate binding, and the monocarboxylic acid compound is reacted in a suspended state. This method can effectively produce a metal complex.
