Abstract: The trimeric Zr6-containing silicotungstate [Zr6O2(OH)4(H2O)3(beta-SiW10O37)3](super 14-) and the dimeric Zr6-containing silicotungstate [Zr4O2(OH)2(H2O)4(beta-SiW10O37)2](super 10-) are synthesized and structurally characterized. Both polyanions are chiral and [Zr6O2(OH)4(H2O)3(beta-SiW10O37)3](super 14-) contains more zirconium centers than any other known polyoxometalate.
