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

In the title salt, C26H27F2N2 +·C4H8O4 -, 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) à was found between one of the fluorinated benzene rings and the non-fluorinated phenyl ring in the neighbouring molecule related by a glide plane
