Abstract: The title compound, (C₉H₈N)₂[Cr₂O₇], crystallizes in the monoclinic space group P2₁/c, with eight cations and four anions in the unit cell. The quinolinium cations and a dichromate anion are connected through N-HO and C-HO intermolecular hydrogen bonds and by aromatic --stacking interactions. The dichromate geometry is normal, with a Cr-O(bridging)-Cr angle of 135.1  (2)°.
