Tetrachloro-oxo-osmium(VI): a new synthesis, and matrix-isolation infrared and ultraviolet–visible studies
Abstract
Pure samples of OsOCl4 have been prepared by a new synthetic route involving OsO4 and BCl3. The i.r. spectrum in low-temperature matrices has been obtained, and exhibits characteristic bands at 1 032 and 395 cm–1. These are assigned as νA1(OsO) and νE(Os–Cl) in a C4v model for monomeric OsOCl4. The electronic spectrum has also been recorded under similar conditions, and tentative assignments proposed for the most intense absorptions.
