【 摘 要 】

In the title compound, C15H18N2O3, the coumarin ring is essentially planar, with an r.m.s. deviation of 0.012 Å. An intra­molecular O—H⋯N hydrogen bond forms an S(6) ring motif. The piperazine ring adopts a chair conformation. In the crystal, a C—H⋯O hydrogen bond generates a C(4) chain motif running along the c axis. The chain structure is stabilized by a C—H⋯π inter­action. The chains are linked by π–π inter­actions [centroid–centroid distance of 3.5745 (11) Å], forming a sheet structure parallel to the bc plane.
