1-[Bis(4-fluoro­phen­yl)meth­yl]-4-[(2Z)-3-phenyl­prop-2-en-1-yl]piperazine-1,4-diium dichloride hemihydrate

The asymmetric unit of the title monohydrated salt, 2C(26)H(28)F(2)N(2) (2+)·4Cl(−.)H(2)O, 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.
