Abstract
The infrared and
ultraviolet spectra of phosphorus(111), arsenic(111), antimony(111) and
bismuth(111) ethylxanthates are compared. The C-O
band position (around 1200 cm-l) decreases monotonically (7 cm-1
intervals) from phosphorus to bismuth. The absorptions in the ultraviolet are
assigned to intraligand and charge-transfer bands.
Bismuth ethylxanthate dissociates appreciably in alcoholic solution. The
tetrakis(ethy1xanthate) ions of antimony(111) and bismuth(111) were isolated as
their tetraethylammonium salts.
