| Abstract: | 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) Å] and either two water O atoms or two tdga carboxyl O atoms Mn—O = 2.1214 (17)–2.1512 (17) Å]. 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 O?O distances of 2.606 (2) and 2.649 (2) Å. The crystal structure is further stabilized by an extensive network of hydrogen bonds involving 13 water molecules. |
