Bis(μ‐pyridine‐2,6‐carboxyl­ato‐O,N,O′:O)­bis­[tri­aqua­manganese(II)]–pyridine‐2,6‐di­carboxylic acid (1/2)

In the structure of the title compound, Mn₂(C₇H₃NO₄)₂(H₂O)₆]·2C₇H₅NO₄, 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.
