Özet

The two new azo dyes p-(p-acetylphenylazo)-o-allylphenol (compound I) and p-(p-bromphenylazo)-o-allylphenol (compound II) have been synthesized and studied by FT-IR, UVeVIS, 1H NMR, 13C NMR techniques, elemental analysis, X-ray structure analysis and TG, DTG, and DTA analyses. Compound I crystallizes in the monoclinic space group P21/c with a=19.6130(15) A ˚ , b =7.3586(6) A ˚ , c=21.4752(15) A ˚ , a=90.00 , b=101.413(6) , g=90.00 , Z=8, V=3038.1(4) A ˚ 3 and the molecules are linked by two intermolecular O/O hydrogen bonds. There are two independent molecules in the asymmetric unit of compound I. Compound II crystallizes in the monoclinic space group Cc with a=4.7194(7) A ˚ , b=24.597(2) A ˚ , c=12.2241(16) A ˚ , a=90.00 , b=96.509(11) , g=90.00 , Z=4, V=1409.9(3)A ˚ 3 and the molecules are linked by O/N and CeH/O intermolecular hydrogen bonds. They are characterized by UVeVIS, FT-IR, 1H NMR, 13C NMR techniques, elemental analysis, TG, DTG, and DTA analyses.
