New tetra(organotin)-decorated boat-like polyoxometalate.

The reaction of Cl(3)Sn(CH(2))(2)COOCH(3), [H(2)P(2)W(12)O(48)](12-) and WO(4)(2-) in acetate buffer solution led to the hydrolysis of estertin into a carboxyethyltin group and the assembly of a new tetra(organotin)-decorated boat-like polyoxometalate.
