The crystal structure of 1,2-bis-(1H-benzimidazol-2-yl)-ethane dihydrochloride (1) was determined by X-ray diffraction at room temperature. The structure of 1 was also characterized by mass, elemental analysis, FT-IR, and NMR spectroscopy techniques. The title compound crystallizes in triclinic system and space group P-1, a = 7.1350, b = 9.6299(1), c = 15.3340(7) angstrom, alpha = 80.67(2), beta = 79.66(2), gamma = 68.395(11)degrees, V = 958.33(10) angstrom(3), Z = 2 . Owing to the anti conformations of -CH2 groups, the entire molecule is relatively flat. H-1-NMR spectra of 1 show AA'XX' system characteristics.
