Spectral characterization and crystal structure of 1,2-bis-(1 H -benzimidazol-2-yl)-ethane dihydrochloride

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) å,α = 80.67 (2),β = 79.66 (2),γ = 68.395 (11) °,v = 958.33 (10) å 3,z = 2. owing to the anti conformations of chgroups,the entire molecule is relatively flat. h 1 -nmr spectra of 1 show aa ′ x x ′ system characteristics. © 2013 aydin tavman and cigdem sayil.
