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) was found between one of the fluorinated benzene rings and the non-fluorinated phenyl ring in the neighbouring molecule related by a glide plane.
