Molecular and electronic structure of heteropolycomplexes
- 23 Downloads
The IR and Raman spectra of heteropolyacids, the anions of which have a Keggin structure (Td), were obtained.
The anions retain their structure in solution. The influence of the central atom on the vibrations of the framework of the anion, as well as the influence of a coordination sphere on the state of the central atom, were studied.
In all cases it is evident that the Mo-O bond is weaker than the W-O bond, which is the cause of the different stability of heteropolyacids.
Vibrational spectroscopy can be a useful source of information on the structure of heteropolyanions in the crystalline form and in solutions.
