4-(2,3-Di­chloro­phen­yl)piperazin-1-ium picrate

The title compound, C(6)H(2)N(3)O(7) (−)·C(10)H(13)Cl(2)N(2) (+), crystallizes with one 1-(2,3-di­chloro-phen­yl)piperazine (DP) cation and one picrate (PA) anion in the asymmetric unit. In the crystal structure, the DP cation and PA anion are inter­connected via several N—H⋯O and C—H⋯O hydrogen bonds. The DP cation and PA anion are further connected through C—Cl⋯π [3.8201 (4), 3.7785 (4) Å] and N—O⋯π [3.7814 (4) Å] inter­actions. The DP cations are further inter­connected via a weak inter­molecular Cl⋯Cl [3.2613 (4) Å] halogen–halogen inter­action. The combination of these supra­molecular inter­actions leads to a herringbone like supra­molecular architecture. [Image: see text]
