The title compound, C17H12N4O3, a pyrido-pyrrolo-pyrimidine derivative, is almost planar. The nitro-benzene ring is inclined to the mean plane of the 8,9-di-hydro-pyrido[2,3-d]pyrrolo-[1,2-a]pyrimidin-5(7H)-one moiety (r.m.s. deviation = 0.023 Å) by 6.8 (1)°. In the crystal, mol-ecules are linked via C-H⋯O and C-H⋯N hydrogen bonds, forming layers parallel to (101).
标题化合物C17H12N4O3，一种吡啶并吡咯并嘧啶衍生物，几乎呈平面状。硝基苯环相对于8,9-二氢吡啶并[2,3-d]吡咯并[1,2-a]嘧啶-5(7H)-酮部分的平均平面倾斜6.8(1)°（均方根偏差 = 0.023 Å）。在晶体中，分子通过C—H⋯O和C—H⋯N氢键相连，形成平行于(101)的层。
