Diazabicyclo[2.2.2]octane-1,4-diium dichromate.
The title compound, (C(6)H(14)N(2))[Cr(2)O(7)], consists of a diazabicyclo[2.2.2]octane-1,4-diium cation and a discrete dichromate anion, which are linked in the crystal by N-H...O hydrogen bonds. The cation is ordered and distorted, owing to the confinement and twist of the hydrogen bonds involved. Two CrO(4) tetrahedra are joined through a shared O atom to form the dichromate anion. Chiral supramolecular chains of the title compound are built up via N-H...O hydrogen bonds, and C-H...O interactions play subordinate roles in forming the structure.
