Two compounds based on polyoxometalates, (4,4'-H2bpy)7(4,4'-Hbpy)[ [image omitted]]2[ [image omitted]] ·10H2O (1) and (4,4'-H2bpy)6(4,4'-bpy)[ [image omitted]]2 · 18H2O (2), have been prepared under hydrothermal conditions and characterized by IR, XPS spectra, TG analyses, and single crystal X-ray diffraction. Both compounds consist of 4,4'-bipyridine units and polyoxometalates: [ [image omitted]]5- for 1 and [ [image omitted]]6- for 2. In addition, 1 contains both Keggin-type and disordered Keggin-type anions, while 2 contains a (H2O)10 water cluster. [ABSTRACT FROM AUTHOR] |
