Two inorganic-organic hybrid polyoxotungstates constructed from tetra-ZrIV-substituted sandwich-type germanotungstates functionalized by tris ligand

Two tetra-ZrIV-substituted sandwiched polyoxotungstate hybrids functionalized by tris ligands were made and characterized, which contain the same [Zr4(μ3-OH)2(H2O)2(tris)2(α-GeW10O37)]12 − clusters, showing 2D layer with 44·62 network and 3D framework with 412·612·84 network, respectively.150
