摘要

In the cation of the title compound, C7H13N2+·C6H2N3O7?, the seven-membered 1,4-diazepine ring forms a twist chair conformation. The two o-nitro groups in the anion are twisted by 35.0?(7) and 36.0?(9)° from the benzene ring. In the crystal, N—H?O hydrogen bonds between the cation and anion along with weak C—H?O hydrogen bonds produce chains along the b axis. C—H?O hydrogen bonds connecting the chains are also present.
