چکیده
In the cation of the title compound, C(7)H(13)N(2) (+)·C(6)H(2)N(3)O(7) (-), 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.
