Abstract: The title compound, [Mn(C₈H₅O₃)₂(C₁₀H₁₄N₂O)₂(H₂O)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-HO hydrogen bond occurs in the complex. In the crystal structure, O-HO hydrogen bonds link the molecules through an R₂²(16) ring motif, forming a one-dimensional chain along the a axis. The - contact between the pyridyl rings [centroid-centroid distance = 3.629 (2) Å] may further stabilize the structure.
