N-Methyl-4-nitro-anilinium chloride.
The asymmetric unit of the title salt, C(7)H(9)N(2)O(2) (+)·Cl(-), contains two independent cations and anions. In the crystal, each N-methyl-4-nitro-anilinium cation is linked to two Cl(-) anions via N-H⋯Cl hydrogen bonds. π-π stacking is observed between the benzene rings of adjacent cations [centroid-to-centroid distances = 3.7684 (14) and 3.7917 (7) Å].
