PROBLEM TO BE SOLVED: To provide a method for producing a cis-dihalogeno-bis(4,4'-dicarboxy-2,2'-bipyridine) ruthenium (II) more industrially simply than a conventional production method. SOLUTION: The method for producing a cis-dihalogeno-bis(4,4'-dicarboxy-2,2'-bipyridine) ruthenium (II) comprises reacting a ruthenium compound represented by formula (1) [RuX<SB>2</SB>(p-cymene)]<SB>2</SB>(1) (Ru is a ruthenium atom; X is a halogen atom) with 4,4'-dicarboxy-2,2'-bipyridine.
