Abstract
The present invention provides a purified metal complex having oxalic acid as a ligand and a method for industrially producing a purified non-aqueous solvent solution of the metal complex at low cost. In the method of the present invention, oxalic acid contained in a non-aqueous solvent solution of a metal complex having oxalic acid as a ligand is decomposed by a reaction with a thionyl halide in a non-aqueous solvent, and the decomposition product of the reaction and the unreacted thionyl halide are removed by deaeration.
