Diaqua­bis­(benzoato-κO)bis­[4,4,5,5-tetra­methyl-2-(pyridin-4-yl-κN)imidazoline-1-oxyl 3-oxide]cobalt(II)

The title compound, [Co(C(7)H(5)O(2))(2)(C(12)H(16)N(3)O(2))(2)(H(2)O)(2)], was obtained from a conventional solvent evaporation method. The complex mol­ecule is centrosymmetric, so pairs of equivalent ligands lie trans to each other in a slightly distorted octa­hedral CoN(2)O(4) geometry. The Co(II) ion is coordinated by the pyridine N atoms from NITpPy ligands [NITpPy is 4,4,5,5-tetra­methyl-2-(pyridin-4-yl)imidazoline-1-oxyl 3-oxide), water O atoms and two monodentate benzoate O atoms. The complex mol­ecules are connected by O—H⋯O hydrogen bonds between water mol­ecules and benzoate ligands, forming chains parallel to [100]. π–π stacking inter­actions between the benzoate ligands with centroid–centroid distances of 3.752 (2) Å connect the chains into layers parallel to (10-1).
