Spectroscopic studies on the hexafluorides of rhenium, osmium, iridium, and platinum isolated in low-temperature matrices

Abstract

The compounds ReF₆, OsF₆, IrF₆, and PtF₆ have been isolated as monomeric species in intert-gas matrices at low temperatures, and characterised by i.r. spectroscopy. Subsequent u.v.–visible studies reveal a complex pattern of electronic absorptions, and a detailed assignment of these in terms of charge transfer, d–d, and intra-configurational transitions is presented.
