Patent ID: 7932411

Claim:
A method for producing a ruthenium complex represented by the following general formula (3): [RuX 2 (L 2 )] n (3) (wherein Ru represents a ruthenium atom, X represents a halogen atom, L 2 represents an aromatic compound, and n is a natural number of 2 or more), the method comprising heating and stirring, in a hermetically-sealed reaction container, a ruthenium complex represented by the following general formula (1): [RuX 2 (L 1 )] n (1) (wherein Ru represents a ruthenium atom, X represents a halogen atom, L 1 represents an aromatic compound, and n is a natural number of 2 or more) and an aromatic compound represented by the following general formula (2): L 2 (2) (wherein L 2 represents an aromatic compound whose boiling point is lower than that of L 1 ).
