In the title compound, C(11)H(11)N(3)O(4), the 3,5-dioxopiperazine ring adopts an envelope conformation, with the N atom connecting to the -CH(2)COOH group on the flap. In the crystal, mol-ecules are linked by O-H⋯N hydrogen bonds to produce a linear chain running along the c axis. π-π stacking is observed between parallel pyridine rings of adjacent mol-ecules, the centroid-centroid distance being 3.834 (2) Å.
在标题化合物C₁₁H₁₁N₃O₄中，3,5 - 二氧代哌嗪环呈信封式构象，其中N原子连接到瓣上的 - CH₂COOH基团。在晶体中，分子通过O - H⋯N氢键相连，形成沿c轴延伸的线性链。在相邻分子的平行吡啶环之间观察到π - π堆积，质心 - 质心距离为3.834 (2) Å。
