The synthesis, characterization, and crystal and molecular structures
of C2H10N22+.Cr2O72- are described. The structure of this compound was
determined by X-ray crystallography and showed that the C2H10N22+ org
anic cations are bound to the Cr2O7- anions by N-H ... O hydrogen-bond
ing interactions [2.988(3) Angstrom and 92.30(17)degrees].
