Diaquabis(1,10-phenanthroline-κ2 N,N′)manganese(II) thiodiglycolate bis(1,10-phenanthroline-κ2 N,N′)(thiodiglycolato-κ2 O,O′)manganese(II) tridecahydrate

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.
