In the title compound, C26H28N2, the piperazine group adopts a chair conformation with the exocyclic N - C bonds in equatorial orientations. The dihedral angle between the geminal benzene rings is 80.46(12)° and the C=C - C - N torsion angle is 145.9(2)°. In the crystal, weak C - H⋯π interactions link the molecules into [100] chains. © 2014 CrossMark. Source

The asymmetric unit of the title monohydrated salt, 2C26H 28F2N2 2+·4Cl -·H2O, consists of a 1-[bis(4-fluorophenyl)-methyl] -4-[(2Z)-3-phenylprop-2-en-1-yl]piperazine-1,4-diium cation with a diprotonated piperizine ring in close proximity to two chloride anions and a single water molecule that lies on a twofold rotation axis. In the cation, the piperazine ring adopts a slightly distorted chair conformation. The dihedral angles between the phenyl ring and the 4-fluorophenyl rings are 89.3 (9) and 35.0 (5)°. The two fluorophenyl rings are inclined at 65.0 (5)° to one another. In the crystal, N-H⋯Cl hydrogen bonds and weak C-H⋯Cl intermolecular interactions link the molecules into chains along [010]. In addition, weak C-H⋯O interactions between the piperizine and prop-2-en-1-yl groups with the water molecule, along with weak C-H⋯Cl interactions between the prop-2en-1-yl and methyl groups with the chloride ions, weak C-H⋯F interactions between the two fluorophenyl groups and weak O-H⋯Cl interactions between the water molecule and chloride ions form a three-dimensional supramolecular network.
