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.
