The asymmetric unit of the title compound, Rb(C(7)H(3)N(2)O(7)), comprises an Rb(+) cation and a 3,5-dinitro-salicylate ligand. The Rb(+) cation is 10-coordinated by O atoms from eight 3,5-dinitro-salicylate anions and is linked by three μ(2)-O atoms, forming a zigzag chain along the b-axis direction, which is further linked by the phenyl groups, giving the three-dimensional framework. The crystal structure involves intra-anionic O-H⋯O hydrogen bonds and strong π-π stacking inter-actions [centroid-centroid distance = 3.6755 (7) Å].
标题化合物[Rb(C₇H₃N₂O₇)]ₙ的不对称单元包含一个Rb⁺阳离子和一个3,5-二硝基水杨酸配体。Rb⁺阳离子由八个3,5-二硝基水杨酸阴离子的O原子进行十配位，并通过三个μ₂-O原子相连，沿b轴方向形成一条锯齿链，该链进一步通过苯基相连，形成三维骨架。晶体结构涉及阴离子内的O—H⋯O氢键和强烈的π-π堆积相互作用[质心间距 = 3.6755 (7) Å]。
