Abstract: In the title compound, [Cu₄(C₄H₄O₄)₂(C₁₂H₈N₂)₄(H₂O)₄](NO₃)₄·4H₂O, the complete tetracation is generated by crystallographic inversion symmetry. Both unique Cu²⁺ ions are coordinated by an N,N'-bidentate phenanthroline molecule, two O-monodentate bis-bridging succinate dianions and a water molecule, resulting in distorted CuN₂O₃ 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-HO hydrogen bonds and aromatic - stacking interactions [minimum centroid-centroid separation = 3.537 (2) Å].
