Diaquabis(1,10-phenanthroline-κ2N,N′)manganese(II) thiodiglycolate bis(1,10-phenanthroline-κ2N,N′)(thiodiglycolato-κ2O,O′)manganese(II) tridecahydrate

The title compound, [Mn(C12H8N2)(2)(H2O)(2)](C4H4O4S).-[Mn(C4H4O4S)(C12H8N2)(2)].13H(2)O, contains one dianion of thiodiglycolic acid (tdga(2-)) 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 Mu(II) atoms are octahedrally coordinated by four N atoms of two bidentate phen ligands [Mn-N = 2.240 (2)-2.3222 (19) Angstrom] and either two water O atoms or two tdga carboxyl O atoms [Mn-O = 2.1214 (17)-2.1512 (17) Angstrom]. 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) Angstrom. The crystal structure is further stabilized by an extensive network of hydrogen bonds involving 13 water molecules.
