The title compound, C(10)H(12)O(5)N(2), crystallizes with two independent molecules in the asymmetric unit. The molecules in the crystal structure are arranged into one-dimensional substructural ribbon motifs stabilized by a combination of two O-H...O and three N-H...O intermolecular hydrogen bonds, and also augmented by short C=O...C=O carbonyl-carbonyl interactions. Two intermolecular C-H...O short contacts between adjacent ribbons generate complex two-dimensional sheets on the ab plane. Adjacent sheets are linked via C-H...pi(arene) interactions, resulting in a complex three-dimensional framework.
标题化合物C(10)H(12)O(5)N(2)在不对称单元中以两个独立分子结晶。晶体结构中的分子排列成一维子结构带状基序,通过两个O-H...O和三个N-H...O分子间氢键的组合得以稳定,并且还因短的C=O...C=O羰基-羰基相互作用而增强。相邻带状结构之间的两个分子间C-H...O短接触在ab平面上形成复杂的二维片层。相邻片层通过C-H...π(芳烃)相互作用相连,形成复杂的三维框架。
