Poly[diaqua­bis­(nitrato-κ(2) O,O′)bis­(1,10-phenanthroline-κ(2) N,N′)-μ(3)-succinato-dicadmium]

In the title coordination polymer, [Cd(2)(C(4)H(4)O(4))(NO(3))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)](n), the Cd(II) ion is seven-coordinated within a distorted penta­gonal–bipyramidal O(5)N(2) 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.
