Synthesis, structure and physical properties of the manganese(II) selenide/selenolate cluster complexes [Mn32Se14(SePh)36(PnPr3)4] and [Na(benzene-15-crown-5)(C4H8O)2]2[Mn8Se(SePh)16]

The synthesis, molecular structures, and magnetic and optical properties of [Mn32Se14(SePh)36(PnPr3)4] and [Na(benzene-15-crown-5)(C4H8O)2]2[Mn8Se(SePh)16] have been investigated which are the first examples of manganese chalcogenide cluster complexes, despite known manganese oxo compounds, which comprise more than four manganese atoms.
