The title compound, (C3H12N2)[Cr2O7], consists of a discrete dichromate anion with here an eclipsed conformation and a propane-1,3-diammonium cation.Both kinds of ions have a mirror plane passing through the bridging O atom and the central methylene C atom of the Cr2O72− and C3H12N22+ moieties, respectively.Anions and cations are alternately stacked to form columns parallel to the b axis.Ions are linked by intra- and inter-column hydrogen bonds of types N—H.O and C—H.

O, involving O atoms of the dichromate anions as acceptors, and ammonium or click here methylene groups as donors.
