Abstract
In the title compound, C(13)H(14)N(2)O(3), the fused ring system is almost planar (r.m.s. deviation = 0.015 Å). The r.m.s. deviation for all the non-H atoms of the mol-ecule is 0.065Å. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds generate polymeric chains along the b axis containing alternating centrsymmetric R(2) (2)(8) and R(2) (2)(20) loops.
摘要
在标题化合物C₁₃H₁₄N₂O₃中，稠环体系几乎是平面的（均方根偏差 = 0.015 Å）。分子中所有非H原子的均方根偏差为0.065 Å。在晶体中，N—H⋯O和C—H⋯O氢键沿b轴生成包含交替中心对称的R₂²⁸和R₂²²⁰环的聚合链。
