The polymeric compound, {(C10H9N2)[Mn(C7H3NO4)2].­(C10H8N2).6H2O}n, was prepared by the reaction of manganese (II) nitrate with pyridine-2,3-dicarboxylic acid, (py-2,3-dcH2) and 4,4'-bipyridine (4,4'-bipy) in a 1:2:4 molar ratio. The crystal system of the complex is monoclinic with space group P21/n and four molecules per unit cell. The unit cell parameters are: a = 22.2099(15) Å, b = 6.6599(4)...
