The title compounds, C7H4I2O2 1 and C13H7I2N2O3 2, have been synthesized and characterized by single-crystal X-ray diffraction. Compound 1 crystallizes in monoclinic, space group P21/c with a = 9.802(2), b = 13.867(3), c = 7.364(2) , β = 109.74(3)o, V = 942.1(3) 3, Dc = 2.636 g/cm3, C7H4I2O2, Mr = 373.90, F(000) = 672, μ = 6.627 mm–1, Z = 4, R = 0.0459 and wR = 0.1018 for 1805 observed reflections (I > 2σ(I)). Compound 2 belongs to the monoclinic system, space group P21/n with a = 9.015(2), b = 12.024(2), c = 14.072(3), β = 103.91(3)o, V = 1480.6(5) 3, Dc = 2.216 g/cm3, C13H7I2N2O3, Mr = 494.01, F(000) = 920, μ = 4.255 mm–1, Z = 4, R = 0.0777 and wR = 0.1757 for 2896 observed reflections (I > 2σ(I)). Compounds 1 and 2 were assayed for antibacterial activities against three Gram positive bacterial strains (B. subtilis, S. aureus and S. faecalis) and three Gram negative bacterial strains (E. coli, P. aeruginosa and E. cloacae) by MTT method. Fortunately, compound 2 is found to show potent antibacterial activity against these six bacterial strains.
