Abstract

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 . 1 3 5 0 , 𝑏 = 9 . 6 2 9 9 ( 1 ) , 𝑐 = 1 5 . 3 3 4 0 ( 7 ) Å, 𝛼 = 8 0 . 6 7 ( 2 ) , 𝛽 = 7 9 . 6 6 ( 2 ) , 𝛾 = 6 8 . 3 9 5 ( 1 1 ) ∘ , 𝑉 = 9 5 8 . 3 3 ( 1 0 ) Å3, 𝑍 = 2 . Owing to the anti conformations of –CH2– groups, the entire molecule is relatively flat. 1 H -NMR spectra of 1 show AA ′ X X ′ system characteristics.
