The 1,5-diaryl-3-cyanoformazans were prepared and subjected to IR, MS, 1 H NMR, and 13 C NMR spectral analysis. The results indicate the presence of a strong intramolecular hydrogen bond in the formazan molecule. Moreover, the two phenyl rings are equivalent and the C'N and NOH stretching vibrationa
