Bis[2-(2-pyridylmethyleneamino)benzenesulfonato-κ3N,N′,O]manganese(II) dihydrate
Abstract
The title complex, [Mn(C12H9N2O3S)2]·2H2O, is isotypic with the previously reported ZnII and CdII species. The complex was prepared by the reaction of the potassium salt of 2-(2-pyridylmethyleneamino)benzenesulfonic acid with MnCl2·6H2O in methanol. The complex displays twofold symmetry, with the ligands coordinated in a tridentate meridional-like arrangement through pyridyl N, imine N, and sulfonate O atoms. The metal center has a strongly distorted octahedral coordination geometry. The uncoordinated water molecules and the complexes participate in a hydrogen-bonding network, forming a two-dimensional structure parallel to the ab plane.
