In the title coordination polymer, [Cd2(C4H4O4)(NO3)2(C12H8N2)2(H2O)2]n, the CdII ion is seven-coordinated within a distorted penta­gonal–bipyramidal O5N2 environment. The succinate anions, located on an inversion centre, adopt a bis-monodentate bridging mode, leading to the formation of rods along [100]. The rods are connected by O—H⋯O hydrogen bonds between the coordinating water mol­ecules and nitrate O atoms of adjacent rods; the same type of hydrogen bonds are also observed between water and carboxyl­ate O atoms within the rods. π–π stacking inter­actions with a minimum plane-to-plane separation of 3.462 (2) Å occur between phenanthroline ligands.
