In the course of studies on hybrid antibacterials incorporating 2-aryl-5-nitro-1H-indole moieties as potential bacterial NorA efflux pump inhibitors, the compound 1-[2-(5-nitro-1H-indol-2-yl)phenyl]methylpyridinium chloride (2) was synthesized and structurally characterized. This pyridinium chloride salt crystallized in the monoclinic space group P2(1)/c with the following unit cell dimensions: a 10.274(3) Å, b 13.101(4) Å, c 13.439(4) Å, b 107.702(7)°, V 1723.2(9) ų, Z (f.u.) = 4; R1 = 0.048, and wR2 = 0.13. Of interest in the single crystal X-ray structure is the (intramolecular) disposition of the pyridinium plane over the indole heterocyclic residue [interplanar dihedral angle 17.91(4)°].
在研究将 2-芳基-5-硝基-1H-吲哚部分作为潜在的细菌 NorA 外排泵抑制剂的混合抗菌剂的过程中，合成并结构表征了化合物 1-[2-(5-硝基-1H-吲哚-2-基)苯基]甲基吡啶鎓氯化物（2）。该吡啶鎓盐以单斜晶系 P2(1)/c 空间群结晶，具有以下晶胞参数：a 10.274(3) Å, b 13.101(4) Å, c 13.439(4) Å, b 107.702(7)°, V 1723.2(9) ų, Z (f.u.) = 4；R1 = 0.048，wR2 = 0.13。在单晶 X 射线结构中，引人注目的是吡啶鎓平面相对于吲哚杂环残基的（分子内）排布[平面间二面角 17.91(4)°]。
