Formation of isopolyoxometallate(VI) anions in the reaction between M(CO)6 (M = W, Mo) and acetic acid: X-ray crystal structure of [W3(μ3-O)2(μ2η2-O2CCH3)6(H2O)3]2[W10O32·solvent

Addition of CH3CO2Na to the above reaction mixture, and prolonged exposure of the solution to air, results in the formation of the WIV/WVI complex salt [W3(μ3-O)2(μ2η2-O2CCH3)6(H2O)3]2[W10O32]·solvent (3). Complex 3 was also prepared by reacting 1 with Na2WO4·2H2O in acetic acid, and it has been characterized by X-ray crystallography. Addition of [CH3(CH2)3]4N(ClO4) to the reaction filtrate remaining after the preparation of [Mo2(μ-O2CCH3)4][from Mo(CO)6, CH3CO2H and (CH3CO)2O], followed by exposure to air, gives ([CH3(CH2)3]4N)2[Mo6O19] (4).
