title: Diaquabis(1,10-phenanthroline-kappa(2)N,N')manganese(II) thiodiglycolate bis(1,10-phenanthroline-kappa(2)N,N')(thiodiglycolato-kappa(2)O,O')manganese(II) tridecahydrate.
abstract: The title compound, [Mn(C(12)H(8)N(2))(2)(H(2)O)(2)](C(4)H(4)O(4)S).[Mn(C(4)H(4)O(4)S)(C(12)H(8)N(2))(2)].13H(2)O, contains one dianion of thiodiglycolic acid (tdga(2-)) and two independent manganese(II) moieties, viz. [Mn(phen)(2)(H(2)O)(2)](2+) and [Mn(tdga)(phen)(2)], where phen is 1,10-phenanthroline. The Mn(II) 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 tdga(2-) dianion is hydrogen bonded to an [Mn(phen)(2)(H(2)O)(2)](2+) ion, with O.O 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.
