Abstract

The title compound, C(14)H(12)N(2)O(4), has twofold imposed crystallographic symmetry in the solid state. The asymmetric unit contains one half-mol-ecule. An intra-molecular C-H⋯O hydrogen bond is formed between the carboxyl-ate O group and one H atom of the aromatic ring such that a five-membered ring is formed. The angle between the planes of symmetry-related aromatic rings is 44.71 (19)°.

摘要

标题化合物C(14)H(12)N(2)O(4)在固态时具有二重晶体学对称性。不对称单元包含半个分子。在羧酸盐O基团与芳环的一个H原子之间形成了分子内C—H⋯O氢键，从而形成了一个五元环。对称相关芳环平面之间的夹角为44.71 (19)°。
