Abstract

In the crystal structure of the title salt, C7H7Cl2N2O2+·Cl−, the chloride anions participate in extensive hydrogen bonding with the aminium cations and indirectly link the mol­ecules through multiple N+—H⋯Cl− salt bridges. There are two independent mol­ecules in the asymmetric unit, related by a pseudo-inversion center. The direct inter­molecular coupling is established by C—H⋯O, C—H⋯Cl and C—Cl⋯Cl− inter­actions. A rare three-center (donor bifurcated) C—H⋯(O,O) hydrogen bond is observed between the methyl­ene and nitro groups, with a side-on intra­molecular component of closed-ring type and a head-on inter­molecular component.
