Abstract

A novel zirconium(IV)-substituted tetramer polyoxotungstate, H₆K₄Na₁₆[Zr₄(Î²-GeW₁₀O₃₈)₂(A-Î±-PW₉O₃₄)₂]Â·37H₂O, was synthesized hydrothermally and characterized by IR spectroscopy, elemental analysis, thermogravimetric analysis, powder X-ray diffraction, energy-dispersive X-ray spectroscopy and single-crystal X-ray diffraction. The compound crystallizes in the monoclinic P2/n space group. The most remarkable feature is that the centrosymmetric Zr-based polyoxotungstate tetramer consists of dilacunary Keggin-type germanotungstate and trilacunary Keggin-type phosphotungstate units that are linked by Zr^IV ions.
