Fecha de publicación: | 2012 | Publicación seriada: | Journal of Solid State Chemistry | Resumen: | Structural changes occurring within non-conventional Dawson-type [α/β-Mo 18O 54(SO 3) 2] 4- 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. | URI: | http://hdl.handle.net/10553/121274 | ISBN: | 00224596 1095726X | ISSN: | 0022-4596 | DOI: | 10.1016/j.jssc.2011.12.005 | Fuente: | Journal of Solid State Chemistry [ISSN 0022-4596], v. 186, p. 171-176 |
