Compounds of Arsenic, Antimony and Bismuth

G. O. Doak and L. D. Freedman, Organometallic Compounds of Arsenic, Antimony, and Bismuth,]ohn Wiley Sons, Inc., New York, 1970. 

There are many organometallic compounds of arsenic, antimony, and bismuth known that constitute series having chemical properties that differ markedly. These compounds generally decrease in stability in the order As > Sb > Bi, which agrees with the increasing difference in size of the atoms and carbon atoms. Arsenic compounds include both aliphatic derivatives and heterocycles such as arsabenzene,...

The sulfur analog, SPC13, and several mixed oxyhalides such as OPCI2F and OPCI2Br are known, but they are not widely used compounds. Oxyhalide compounds of arsenic, antimony, and bismuth are of much less importance than are those of phosphorus.
