The title compound, CHNO ·CHClN , crystallizes with one 1-(2,3-di-chloro-phen-yl)piperazine (DP) cation and one picrate (PA) anion in the asymmetric unit. In the crystal structure, the DP cation and PA anion are inter-connected 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] inter-actions. The DP cations are further inter-connected a weak inter-molecular Cl⋯Cl [3.2613 (4) Å] halogen-halogen inter-action. The combination of these supra-molecular inter-actions leads to a herringbone like supra-molecular architecture.
标题化合物CHNO·CHClN在不对称单元中结晶，含有一个1-(2,3-二氯苯基)哌嗪(DP)阳离子和一个苦味酸盐(PA)阴离子。在晶体结构中，DP阳离子和PA阴离子通过几个N-H⋯O和C-H⋯O氢键相互连接。DP阳离子和PA阴离子还通过C-Cl⋯π [3.8201 (4), 3.7785 (4) Å]和N-O⋯π [3.7814 (4) Å]相互作用进一步连接。DP阳离子通过弱分子间Cl⋯Cl [3.2613 (4) Å]卤-卤相互作用进一步相互连接。这些超分子相互作用的组合导致了类似人字形的超分子结构。
