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. |

1. A method for producing a metal complex comprising a multivalent carboxylic acid compound, at least one metal ion of a metal belonging to Groups 2 to 13 of the periodic table, an organic ligand capable of multidentate binding to the metal ion, and a monocarboxylic acid compound,
the method comprising reacting the multivalent carboxylic acid compound, the at least one metal ion, the organic ligand, and the monocarboxylic acid compound in a single stage or multiple stages, to form the metal complex, wherein: in the reacting, the metal ion is 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 the monocarboxylic acid compound is the counter anion of the metal ion; and at least two of the multivalent carboxylic acid compound, the metal ion, the organic ligand, and the monocarboxylic acid compound are reacted in a suspended state so that a concentration of each of the at least two of the components in the reaction system after addition is equal to or greater than its saturated solubility. |
