Diaqua­bis(N,N-diethyl­nicotinamide-κN (1))bis­(4-formyl­benzoato-κO (1))manganese(II)

The title compound, [Mn(C(8)H(5)O(3))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], contains one Mn(II) atom lying on an inversion centre, two 4-formyl­benzoate and two diethyl­nicotinamide ligands and two coordinated water mol­ecules. All ligands are monodentate. The four O atoms around the Mn atom form a slightly distorted equatorial plane, while the distorted octa­hedral coordination is completed by the two N atoms in the axial positions. An intra­molecular O—H⋯O hydrogen bond occurs in the complex. In the crystal structure, O—H⋯O hydrogen bonds link the mol­ecules through an R (2) (2)(16) ring motif, forming a one-dimensional chain along the a axis. The π–π contact between the pyridyl rings [centroid–centroid distance = 3.629 (2) Å] may further stabilize the structure.
