Synthesis, Crystal Structure and DNA Interaction of N-(Benzimidazol-2-ylmethyl)-5-chlorosalicylideneimine
The title compound, N-(benzimidazol-2-ylmethyl)-5-chlorosalicylideneimine, has been synthesized and characterized by X-ray single-crystal diffraction. It crystallizes in the monoclinic system, space group P21/n, with a = 8.3765(2), b = 18.1398(4), c = 9.4764(3) A, β = 112.141(2)°, V= 1333.74(6) A3, Mr = 285.73, Z = 4, Dc = 1.423 g/cm3, F(000) = 592, μ= 0.285 mm-1, the final R = 0.0538 and wR = 0.1456 for 1917 observed reflections with I > 2σ(Ⅰ). The fluorescence quenching of the title compound by DNA with Stern-Volmer constant of 2.8×104 M1 indicates that it binds to double-stranded DNA in a partial intercalation mode.
