Abstract

A monomeric tricobalt(II)-substituted phosphotungstate polyanion, [H<sub>9</sub>P<sub>2</sub>W<sub>15</sub>O<sub>62</sub>Co<sub>3</sub>]<sup>9-</sup>, is stabilized by the attachement of an organometallic group, {Mn(CO)<sub>3</sub>}, for the first time. The resulting polyoxometalate-supported [Mn(CO)<sub>3</sub>]<sup>+</sup> complex (1) can be used as an efficient catalyst in the cycloaddition of CO<sub>2</sub> with epoxides under mild reaction conditions with pyrrolidinium bromide as a cocatalyst. Besides, magnetic measurements show that the compound exhibits weaker ferromagnetic interactions at low temperature.
