Diaqua­Bis(N,N-Diethyl­Nicotinamide-Κn1)Bis­(4-Formyl­Benzoato-Κo1)Manganese(Ii)

Abstract

The title compound, [Mn(C8H5O3)2(C10H14N2O)2(H2O)2], contains one MnII 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.
