Abstract :
The asymmetric unit of the title compound, C14H18N2O4, contains two independent molecules (A and B) which have essentially the same conformation. The piperazine rings adopts chair conformations with the N atoms out of plane. The dihedral angles formed by the four approximately planar C atoms of the piperazine ring and the benzene ring is 30.8 (5)° in molecule A and 30.6 (5)° in molecule B. In the crystal, molecules A and B are connected by a pair of O—H⋯O hydrogen bonds, forming a dimer with graph-set notation R22(8). Weak C—H⋯O hydrogen bonds connect the dimers, forming zigzag chains along [001].
