Abstract

A novel dinuclear zirconium sandwich-type silicotungstate cluster of [(γ-SiW ₁₀O ₃₆) ₂Zr ₂(μ-OH) ₂] ^10- (1) was synthesized by the reaction of a divacant lacunary γ-Keggin silicotungstate [γ-SiW ₁₀O ₃₆] ^8- with ZrOCl ₂·8H ₂O. The anion consisted of two [γ-SiW ₁₀O ₃₆] ^8- units sandwiching a diamond Zr ₂(μ-OH) ₂ core, and each zirconium atom in 1 was six-coordinated to two μ-OH ligands and four oxygen atoms of two [γ-SiW ₁₀O ₃₆] ^8- units. The Zr ₂(μ-OH) ₂ core in 1 reacted with methanol to give the corresponding monomethoxo derivative [(γ-SiW ₁₀O ₃₆) ₂Zr ₂(μ-OH)(μ-OCH ₃)] ^10- (2).
