Özet |
The asymmetric unit of the title compound, [Mn(C7H4NO4)2(C6H6N2O)2(H2O)2], contains one MnII atom, one 4-nitrobenzoate (NB) anion, one nicotinamide (NA) ligand and one water molecule; NA and NB each act as a monodentate ligand. The MnII atom, lying on an inversion centre, is coordinated by four O atoms and two pyridine N atoms in a distorted octahedral geometry. The water molecules are hydrogen bonded to the carboxylate O atoms. The dihedral angle between the carboxylate group and the adjacent benzene ring is 24.4(3)°, while the benzene and pyridine rings are oriented at a dihedral angle of 86.63(11)°. In the crystal, O - H⋯O and N - H⋯O hydrogen bonds link the molecules, forming a layer parallel to the ab plane. The layers are further linked via weak C - H⋯O hydrogen bonds, a π-π stacking interaction [centroid-centroid distance = 3.868(2)A] and a weak C - H⋯π interaction, resulting in a three-dimensional network. |
