Triaqua­(cyclo­hex-4-ene-1,2-dicarboxyl­ato-κO (1))(1,10-phenanthroline-κ(2) N,N′)cobalt(II)

In the title compound, [Co(C(8)H(8)O(4))(C(12)H(8)N(2))(H(2)O)(3)], the Co(II) atom is coordinated by two N atoms from a bidentate 1,10-phenanthroline ligand, one O atom from a monodentate 4-cyclo­hexene-1,2-dicarboxyl­ate ligand and three water O atoms in a distorted octa­hedral geometry. The mononuclear mol­ecules are engaged in extensive intra- and inter­molecular O—H⋯O hydrogen-bonding inter­actions and π–π stacking inter­actions [centroid–centroid distance = 3.784 (3) Å], forming a three-dimensional supra­molecular network.
