In this study 1-substituted phenyl-3,5-diphenylformazans were synthesized from benzaldehyde-N-phenylhydrazone and appropriate phenyldiazonium salts having CH3, Br, and Cl at the o-, m-, and p-positions of 1-phenyl ring. Their structures were determined by infrared and ultraviolet–visible spectra. Bathochromic effect in accordance with the electron-donating effect of CH3, Br, and Cl group and its magnitude
