Abstract: In the titile compound, C₁₈H₂₀Cl₂N₂O₂, the piperazine ring adopts a chair conformation. The molecule has a non-crystallographic inversion centre in the middle of the piperazine ring at approximate position (3/4, 1/8, 3/8). There are intramolecular O-HN hydrogen bonds forming S(6) ring motifs. Intermolecular C-HO hydrogen bonds generate antiparallel C(5) chain motifs propagating along the b axis, forming sheets parallel to the bc plane with a first-level graph-set S(6)C(5)R₆⁶(26).
