title: Diaqua-bis(N,N-diethyl-nicotinamide-κN)bis-(4-formyl-benzoato-κO)manganese(II).
abstract: 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-formyl-benzoate and two diethyl-nicotinamide ligands and two coordinated water mol-ecules. All ligands are monodentate. The four O atoms around the Mn atom form a slightly distorted equatorial plane, while the distorted octa-hedral coordination is completed by the two N atoms in the axial positions. An intra-molecular O-H⋯O hydrogen bond occurs in the complex. In the crystal structure, O-H⋯O hydrogen bonds link the mol-ecules 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.
