Organobismuth Compounds. III. Preparation and Infrared Spectra of Triphenylbismuth(V) Derivatives of Dibasic Acids

Abstract

Triphenylbismuth carbonate, oxalate, sulfate, selenate, and chromate have been prepared and their solid state infrared (i.r.) spectra have been studied in the frequency region 4000 to 200 cm −1 . The i.r. spectroscopic results indicate that, like the corresponding trimethyl- and triphenylantimony(V) derivatives, these compounds also have non-ionic polymeric structures containing bridging anion groups and five co-ordinate bismuth. The i.r. frequencies associated with the bismuth–anion stretching vibrations appear to occur at 300 cm −1 for the carbonate and below 300 cm −1 for the other compounds.
