The title compound, (C(5)H(6)N(3)O(2))(2)[Cr(2)O(7)], consists of 2-amino-3-nitro-pyridinium cations and discrete dichromate anions linked together by N-H⋯O and C-H⋯O hydrogen bonds, forming thick layers parallel to (101). Layer cohesion is ensured by N-H⋯O hydrogen bonding in addition to electrostatic and van der Waals inter-actions, forming a three-dimensional framework. The dichromate anion is located on a twofold axis that passes through its bridging O atom.
标题化合物（C₅H₆N₃O₂）₂[Cr₂O₇]由2-氨基-3-硝基吡啶鎓阳离子和离散的重铬酸根阴离子通过N-H⋯O和C-H⋯O氢键连接在一起，形成平行于（101）的厚层。除了静电和范德华相互作用外，通过N-H⋯O氢键确保层间凝聚，形成三维框架。重铬酸根阴离子位于穿过其桥连O原子的二重轴上。
