Schiff-base compound 2-{[4-(Phenyldiazenyl)-phenyl]iminomethyl}-5-bromophenol (1), containing an azo group was synthesized from the reaction of p-aminoazobenzene with 5-bromosalicylaldehyde and characterized by elemental analyses, FT-IR spectroscopy and X-ray single-crystal diffraction analysis. Molecular orbital calculation has been carried out using density functional method (B3LYP) at 6-31G basis set. Compound 1 crystallizes in the orthorhombic system, space group Pca21, with a = 12.1781(2) A, b = 4.4894(10) A, c = 27.7841(5) A, and Z = 4. Compound 1 displays a trans configuration with respect to the C=N and N=N double bonds.
