Abstract

In the title mol-ecule, C(10)H(8)N(2)O(4), the imidazolidine ring adopts a twisted conformation. In the crystal, the mol-ecules are linked via a pair of bifurcated inter-molecular O-H⋯O hydrogen bonds, forming an inversion dimer. The dimers are further linked via N-H⋯O hydrogen bonds into a tape along the b axis.

摘要

在标题分子C(10)H(8)N(2)O(4)中，咪唑烷环呈扭曲构象。在晶体中，分子通过一对分叉的分子间O-H⋯O氢键相连，形成一个反演二聚体。这些二聚体通过N-H⋯O氢键进一步沿b轴连接成一条带。
