Abstract

The title compound, C(17)H(18)N(2)O(4), crystallizes with two independent mol-ecules in the asymmetric unit. The two benzene rings in each mol-ecule make dihedral angles of 7.6 (3) and 3.9 (3)°. Intra-molecular O-H⋯N and O-H⋯O hydrogen bonds are present in each mol-ecule. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into chains propagating in [010]. The are also a number of C-H⋯O and π-π inter-actions present [centroid-centroid distances = 3.874 (4) and 3.904 (3) Å], that result in the formation of a three-dimensional network.

摘要

标题化合物C(17)H(18)N(2)O(4)在不对称单元中以两个独立分子结晶。每个分子中的两个苯环形成的二面角分别为7.6 (3)°和3.9 (3)°。每个分子中存在分子内O-H⋯N和O-H⋯O氢键。在晶体中，N-H⋯O氢键将分子连接成沿[010]方向延伸的链。还存在许多C-H⋯O和π-π相互作用[质心-质心距离 = 3.874 (4) 和3.904 (3) Å]，导致形成三维网络。
