3-Chloro-4-fluoro­anilinium picrate

In the title picrate salt of a dihalogenated aniline derivative, C₆H₆ClF⁺·C₆H₂N₃O₇⁻, the intra­cyclic C—C—C angles in the picrate anion cover a broad range [111.95 (12)–125.38 (13)°], while those in the aromatic cation span a much narrower range [118.25 (14)–122.33 (13)°]. In the crystal, classical N—H...O hydrogen bonds, as well as C—H...O contacts, connect the ions into layers parallel to (001).

4-[Bis(4-fluoro­phen­yl)meth­yl]-1-[(2E)-3-phenyl­prop-2-en-1-yl]piperazin-1-ium 3-carb­oxy­propano­ate

In the title salt, C₂₆H₂₇F₂N₂⁺·C₄H₅O₄⁻, the piperazine N atom bearing the vinylic substituent is protonated. The piperazine ring adopts a chair conformation. In ther crystal, the succinate monoanions are connected via short O—H...O hydrogen bonds between the carb­oxy­lic acid and carboxyl­ate groups into undulating chains extending along [001] and the flunarizinium monocations are attached to these chains via N⁺—H...O⁻ hydrogen bonds. C—H...O inter­actions connect these chains into a three-dimensional network. The shortest centroid–centroid distance of 3.7256 (10) Å was found between one of the fluorinated benzene rings and the non-fluorinated phenyl ring in the neighbouring mol­ecule related by a glide plane.
