The title compound, C19H20N4OSCl2, crystallizes in the monoclinic system, space group P21/c, with cell constants a = 15.470(3)Å, b = 9.577(2)Å, c = 14.615(3)Å and Z = 4. The piperazine ring adopts a chair conformation. A weak conjugation effect of the lone pair of the tertiary N atom with the π-electron system of the phenyl ring is observed. The molecular packing is influenced by the C-H…O and C-H…N intermolecular hydrogen bonds.
