N2 - By the hydrothermal technique, two new organic–inorganic hybrids, tetra-Zr-substituted sandwich-type germanotungstate clusters functionalized by different organic amines H10K4[Zr4(μ3-O)2(μ-OH)2(enMe)2(B-α-GeW10O37)2]·6DMF·18H2O (1) and H10K2Na2[Zr4(μ3-O)2(μ-OH)2(en)2(B-α-GeW10O37)2]·4 DMF·22H2O (2) (enMe = 1,2-diaminopropane, en = ethylenediamine, DMF = N,N-dimethylformamide) have been obtained, which have been characterized by single-crystal X-ray structure analysis, powder X-ray diffraction (PXRD), elemental analysis, FT-IR spectra and thermogravimetric analysis (TGA), respectively. The structure analysis reveals that 1 and 2 exhibit similar sandwich-type polyoxoanion built by two [Zr2(μ3-O)(μ-OH)(enMe)(B-α-GeW10O37)] or [Zr2(μ3-O)(μ-OH)(en)(B-α-GeW10O37)] clusters, showing the first germanotungstate clusters with Zr-containing 5-membered ring formed from the chelation coordination pattern of Zr4+ and organic amine. To compounds 1 and 2, the cluster units, [Zr4(μ3-O)2(μ-OH)2(enMe)2(B-α-GeW10O37)2] and [Zr4(μ3-O)2(μ-OH)2(en)2(B-α-GeW10O37)2], are linked by K+ cations to form 1-D chains, respectively.
