Mechanism of the Color Reaction of Active Methylene Compounds with 1, 3, 5-Trinitrobenzene Derivatives. IX. Crystalline 1 : 2 Complex of Picric Acid and Creatinine

Abstract

1 : 2 Complex of picric acid and creatinine was isolated in crystalline forms from the alkaline reaction mixture of creatinine and excess picric acid. Structural characterization of the complex and its absorption spectral behavior were discussed.
