In the cation of the title salt, (C12H14N2)[Cr2O7], the two pyridinium moieties are in an anti orientation with respect to one another. The dihedral angle between the pyridine rings is 6.3 (2)°. The N-C-C-N torsion angle is 177.5 (2)°. In the dianion, the CrVI ions are in a slightly distorted tetra­hedral coordination environment and the bond angles at the independent CrVI ions are in the ranges 105.93 (10)-110.60 (11) and 107.35 (11)-111.07 (12)°. The Cr-O-Cr angle is 127.96 (12)°. The crystal used was an inversion twin with refined components of 0.510 (19) and 0.490 (19).
