Notizen:
The low temperature Raman and far-infrared (IR) spectra of solution-grown crystals of K2PtCl6:Ir4+ have been studied. In addition to the strong absorptions of the host compound, a number of weak features were observed. The Raman band at 278 cm-1 has been assigned to ν2(Eg) of IrCl62-. An IR- and Raman-active band, observed at 236 cm-1 when K2IrBr6 was used as the dopant, has been assigned to ν(Pt-Br), A1g′ of [PtCl4Br2]2-. The symmetry of the host compound was lowered by the presence of the dopant ions, resulting in a splitting of some of the IR-active degenerate modes. Preliminary Raman experiments with K2PtCl6:Os4+ indicated that ν2 of OsCl62- was at 271 cm-1.
