Spectroscopic studies of sulfite-based polyoxometalates at high temperature and high pressure
Abstract
Structural changes occurring within non-conventional Dawson-type [α/β-Mo O (SO ) ] polyanions in the form of tetrapentylammonium salts were studied by a combination of IR, Raman and visible spectroscopy at high temperature and high pressure. Evidence of the formation of bronze-type materials above 400 K and also upon pressurization to 8 GPa is presented. This conclusion is suggested to be a general result for polyoxometalate compounds subjected to extreme conditions and it opens opportunities for the design of new materials with interesting optical and electronic properties. © 2011 Elsevier Inc.
