Two supramolecular compounds based on Keggin-type polyoxometalates (POMs), (4,4′-H2bpy)(4,4′-Hbpy)[PMo12O40] (1) and (4,4′-H2bpy)(4,4′-Hbpy)2[SiW12O40] · 4H2O (2), have been synthesized hydrothermally and characterized by elemental analyses, IR, UV-Vis, XPS spectra, thermogravimetric analyses, and single-crystal X-ray diffraction analyses. The two compounds consist of 4,4′-bipyridine (4,4′-bpy) ligands and different Keggin-type POMs which are [PMo12O40]3−for1and [SiW12O40]4−for2. There are hydrogen-bonding interactions between the POMs, 4,4′-bipyridine, and/or water in1and2. In addition,2contains an uncommon (H2O)2water cluster. [ABSTRACT FROM PUBLISHER] |
