A Monomeric Tricobalt(II)-Substituted Dawson-Type Polyoxometalate Decorated by a Metal Carbonyl Group: [P2W15O56Co3(H2O)(3)(OH)(3)Mn(CO)(3)](8-)
A monomeric tricobalt(II)-substituted phosphotungstate polyanion, [H9P2W15O62Co3](9-), is stabilized by the attachement of an organometallic group, {Mn(CO)(3)}, for the first time. The resulting polyoxometalate-supported [Mn(CO)(3)](+) complex (1) can be used as an efficient catalyst in the cycloaddition of CO2 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.
