Résumé

The two independent MnII ions in the polymeric title compound, {[Mn2(C6H2N2O4)(C10H8N2)(H2O)6]SO4·3H2O}, exhibit distorted MnN2O4 octahedral coordination geometries, with the pyrimidine-4,6-dicarboxylate (pmdc) ligand acting in the bis-chelating [mu]-([kappa]O,[kappa]N:[kappa]O',[kappa]N') bridging mode and the 4,4'-bipyridine (bpy) ligand in the [mu]-([kappa]N:[kappa]N') bridging mode. The remaining coordination sites are occupied by O atoms of water molecules. As a consequence, cationic chains of [Mn2([mu]-pmdc)([mu]-4,4'-bpy)(H2O)6]2+ are generated, which extend approximately along the a axis. Sulfate counter-anions and three uncoordinated water molecules complete the structure, which is stabilized by multiple O-H...O hydrogen-bonding interactions between the structural units.
