Spectral Characterization and Crystal Structure of 1,2-Bis-(1H-benzimidazol-2-yl)-ethane Dihydrochloride

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 of1was 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)Å3,Z=2. Owing to theanticonformations of –CH2– groups, the entire molecule is relatively flat.H1-NMR spectra of1show AA′XX′system characteristics.
