Two novel heteropolytungstates K[M(phen)2(H2O)]2[PW12O40] · 2H2O (M = Fe 1, Cu 2, phen = 1,10′-phenanthroline)have been synthesized and characterized by IR and single crystal X-ray diffraction. The two compounds are isomorphous and crystallized in the space group P1¯. They exhibit interesting 1D chainlike architectures assembled by potassium ions bridged bisupporting Keggin units. To our knowledge, it is the first time that supported polyoxoanions are linked by alkali metals into extended structures.
Two novel heteropolytungstates K[M(phen)2(H2O)]2[PW12O40] · 2H2O (M=Fe 1, Cu 2, phen = 1,10′-phenanthroline) have been hydrothermally prepared, in which bisupporting Keggin units are joined, for the first time, by potassium cations into unprecedented one-dimensional chains.Figure optionsDownload as PowerPoint slide
