摘要：
In the structure of the title compound, [Mn-2(C7H3NO4)(2)(H2O)(6)]. 2C(7)H(5)NO(4), a centrosymmetric dinuclear complex, hexaaaquabis(pyridine-2,6-dicarboxylato)dimanganese(II) and free pyridine-2,6-dicarboxylic acid are present in a 1:2 ratio. In the complex, each Mn2+ ion is coordinated by three O atoms and one N atom from the pyridine-2,6-dicarboxylate ligands and by three water O atoms, resulting in a distorted pentagonal bipyramidal coordination. Within the centrosymmetric dinuclear complex, two Mn2+ ions are bridged by two carboxylate O atoms. The crystal structure is stabilized by hydrogen bonds involving all the H atoms of the water ligands.
