Two manganese-amine complexes incorporating thioantimonates and exhibiting diversiform roles of amine ligands

Two manganese-amine complexes incorporating thioantimonates, namely (dienH3)[(dienH)MnSb8S15]center dot H2O (dien = diethylenetriamine) (1) and[Mn(teta)(H2O)(2)](2)[Mn(tren)] 2Sb3S12 center dot H3O (2, teta = triethylenetetramine, tren = tris(2-aminoethyl)amine), have been solvothermally synthesized and structurally characterized. Interestingly, the organic amines show diversiform structure-directing actions in the title compounds. In compound 1, two dien molecules exhibit partial coordination to Mn2+ ions and protonated cations, and compound 2 contains mixed tetradentate tren and teta chelating amines. The optical properties, thermal stabilities and magnetic properties have also been studied.
