| Abstract: | The X-ray crystal structure of benzimidazolium dichromate is determined. The compound C14H14Cr2N4O7 is Triclinic in P-1 with a = 8.2722(8) Å, b = 10.0269(10) Å, c = 11.7001(11) Å,  = 102.073(2)°,  =100.483(2)°,  = 67.288(2)°, V = 869.88(15) Å3, Dcalc = 1.734 g/cm3, and Z = 2. A dichromate ion connects two benzimidazolium rings via hydrgen bonds, as leads to face-to-face intramolecular aromatic stacking. The major force of crystal formation comes from hydrogen bonds, and an intermolecular hydrogen bridge is formed to connect two neighbored dichromate ions. |
