In the title salt, C(21)H(24)ClFNO(2) (+)·C(6)H(2)N(3)O(7) (-), the dihedral angle between the aromatic rings in the cation is 16.5 (1)°. The piperidium ring adopts a slightly distorted chair conformation. Strong hydrogen-bonding inter-actions occur between the N-H and O-H functions of the 4-hydroxy-piperidin-1-ium ring and the phenolate and p-NO(2) O atoms of the picrate anion. In addition, a variety of weak C-H⋯O and π-π ring inter-actions between cations and cation-anion neighbors [centroid-centroid distances = 3.597 (1) and 3.848 (10) Å] further consolidate the packing.
在标题盐C(21)H(24)ClFNO(2)(+)·C(6)H(2)N(3)O(7)(-)中，阳离子中芳环之间的二面角为16.5 (1)°。哌啶环呈轻微扭曲的椅式构象。4-羟基哌啶-1-鎓环的N-H和O-H官能团与苦味酸盐阴离子的酚盐和对硝基O原子之间存在强氢键相互作用。此外，阳离子与阳离子-阴离子相邻体之间的各种弱C-H⋯O和π-π环相互作用[质心-质心距离 = 3.597 (1) 和3.848 (10) Å]进一步巩固了堆积。
