Bis(3-carb­oxy-5-nitro­benzoato)bis­[2-(pyridin-4-yl)-1H-imidazo[4,5-f][1,10]phenanthroline]manganese(II)

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-cyclo­penta­[f][1,10]phenanthroline (pcp) ligands and two carboxyl­ate O atoms from two monodentate 3-carb­oxy-5-nitro­benzoate anions in a distorted cis-MnO(2)N(4) octa­hedral 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, mol­ecules are linked by O—H⋯N and N—H⋯O hydrogen bonds. Several aromatic π–π stacking inter­actions [shortest centroid–centroid separation = 3.516 (3) Å] are also observed.
