Structure of 5-Allyl

Abstract

5 - allyl - 2 - hydroxy -3 - methoxyazobenzene was preperad by the reaction of 4 - allyl - 2 - methoxyfenol and benzenediazoniumchloride and crystallized from dimethylsulphoxide to yield crystals suitable for analysis. The molecular structure was identified by UV-VIS, IR, 1H-NMR, 13C-NMR and elemental analysis. The crystal structure of the title compound was determined as monoclinic by by single crystal X-Ray diffraction technique. The crystal parameters of this compound are as follows: monoclinic P 2 1/n, a=5.559(2) Å,b=14.900(2) Å, c= 17.573(29 Å, β= 98.58(1)°, V = 1439.3(2) Å3, Z = 2, Dx = 0.610 g/cm3, F(000) = 284, λ (MoKα) = 0.71070 Å, μ = 0.041 mm-1. The structure was solved by SHELXS-86 and refined by SHELXL-93. R = 0.09 for 1107 observed reflections with I > 2σ (I).
