Abstract: In the title compound, C₁₆H₁₆N₄O₂, the piperazine ring adopts a chair conformation. The title molecule has a crystallographically imposed centre of symmetry with half the molecule constituting the asymmetric unit. Molecules of (I) are linked into a three-dimensional framework by weak C-HO and C-HN interactions. The packing is further stabilized by C-H and - interactions.
