In the title compound, [Mn(C(8)H(4)NO(6))(2)(C(18)H(11)N(5))(2)], the Mn(II) atom is six-coordinated by two N,N'-bidentate 6-(pyridin-4-yl)-5H-cyclo-penta-[f][1,10]phenanthroline (pcp) ligands and two carboxyl-ate O atoms from two monodentate 3-carb-oxy-5-nitro-benzoate anions in a distorted cis-MnO(2)N(4) octa-hedral arrangement. Within the pcp ligands, the dihedral angles between the polycyclic skeletons and pendant pyridine rings are 6.2 (2) and 8.3 (2)°. In the crystal, mol-ecules are linked by O-H⋯N and N-H⋯O hydrogen bonds. Several aromatic π-π stacking inter-actions [shortest centroid-centroid separation = 3.516 (3) Å] are also observed.
在标题化合物[Mn(C₈H₄NO₆)₂(C₁₈H₁₁N₅)₂]中，Mn(II)原子由两个N,N'-双齿的6-(吡啶-4-基)-5H-环戊并[f][1,10]菲咯啉（pcp）配体以及来自两个单齿3-羧基-5-硝基苯甲酸根阴离子的两个羧酸根O原子以扭曲的顺式-MnO₂N₄八面体排列方式进行六配位。在pcp配体中，多环骨架与悬垂吡啶环之间的二面角分别为6.2 (2)°和8.3 (2)°。在晶体中，分子通过O—H⋯N和N—H⋯O氢键相连。还观察到了几种芳香π-π堆积相互作用[最短质心-质心间距 = 3.516 (3) Å]。
