In the racemic title compound, C(14)H(11)N(3)O(3), the pyrimidine ring has an envelope conformation with the puckering parameters Q = 0.3338 (17) Å, Θ = 60.1 (3) and ϕ = 290.4 (3)°. The two N-H groups form hydrogen bonds with symmetry-related mol-ecules, building a two-dimensional network parallel to the (10) plane.
在消旋标题化合物C₁₄H₁₁N₃O₃中，嘧啶环呈信封式构象，褶皱参数Q = 0.3338 (17) Å，Θ = 60.1 (3)，ϕ = 290.4 (3)°。两个N-H基团与对称相关的分子形成氢键，构建了一个平行于(10)平面的二维网络。
