Copper chelates of 1, 6-dihydroxyphenazine and its di-N-oxide, which possess two functional groups, were examined by spectrophotometric method concerning their properties and compositions in solution, as well as their dissociation constants. 1, 6-Dihydroxyphenazine forms a five-membered chelate ring, indicating the molar ratio of 1 : 1, a normal complex. The N-oxide derivative also form a chelate with molar ratio of 1 : 1, forming a six-membered chelate ring.
