Synthesis and Characterization of a Novel Dimer of Di(μ-oxo)manganese Dimers with Two Coordinated Water Molecules in (III,IV,III,IV) Oxidation State

A dimer of di(μ-oxo)dimanganese(III,IV) dimers with two coordinated water molecules, [{Mn2(tmdp)(O)2(H2O)}2] (CF3SO3)4·6H2O, was prepared, where Htmdp is 1,5-bis[bis(2-pyridylmethyl)amino]-3-pentanol, and its crystal structure was determined by X-ray structure analysis. The complex cation consists of two di(μ-oxo)Mn2(III,IV) dimers which are linked by two tmdps to form a dimer of dimers with a bilayered structure.
