Description	The title compound, [Mn(C12H8N2)2(H2O)2](C4H4O4S).[Mn(C4H4O4S)(C12H8N2)2].13H2O, contains one dianion of thiodiglycolic acid (tdga2-) and two independent manganese(II) moieties, viz. [Mn(phen)2(H2O)2]2+ and [Mn(tdga)(phen)2], where phen is 1,10-phenanthroline. The MnII atoms are octahedrally coordinated by four N atoms of two bidentate phen ligands [Mn-N = 2.240 (2)-2.3222 (19) A] and either two water O atoms or two tdga carboxyl O atoms [Mn-O = 2.1214 (17)-2.1512 (17) A]. The tdga ligand chelates as an O,O'-bidentate ligand, forming an eight-membered ring with one Mn atom. The free tdga2- dianion is hydrogen bonded to an [Mn(phen)2(H2O)2]2+ ion, with OO distances of 2.606 (2) and 2.649 (2) A. The crystal structure is further stabilized by an extensive network of hydrogen bonds involving 13 water molecules.
