Di-μ(4)-succinato-tetra­kis[aqua­phenanthrolinecopper(II)] tetra­nitrate tetra­hydrate

In the title compound, [Cu(4)(C(4)H(4)O(4))(2)(C(12)H(8)N(2))(4)(H(2)O)(4)](NO(3))(4)·4H(2)O, the complete tetra­cation is generated by crystallographic inversion symmetry. Both unique Cu(2+) ions are coordinated by an N,N′-bidentate phenanthroline mol­ecule, two O-monodentate bis-bridging succinate dianions and a water mol­ecule, resulting in distorted CuN(2)O(3) square-based pyramidal geometries for the metal ions, with the water mol­ecule occupying the apical site. In the crystal, the components are linked by O—H⋯O hydrogen bonds and aromatic π–π stacking inter­actions [minimum centroid–centroid separation = 3.537 (2) Å].
