Abstract
In the title zwitterionic mol-ecule, C(11)H(9)N(3)O(4), the imidazole and pyridine rings form a dihedral angle of 2.60 (2)°. An intra-molecular O-H⋯O hydrogen bond occurs. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into inversion dimers. Weak inter-molecular C-H⋯O inter-actions further consolidate the crystal packing.
摘要
在两性离子分子C(11)H(9)N(3)O(4)中，咪唑环和吡啶环形成的二面角为2.60 (2)°。存在分子内O—H⋯O氢键。在晶体中，N—H⋯O氢键对将分子连接成反演二聚体。弱的分子间C—H⋯O相互作用进一步巩固了晶体堆积。
