Diphenyl antimony, structure

Gibbons, M.N. Silvestru. C. Haiduc. I. Sowerby, D.B. Reduction of antimony(V) by dithiophosphinates and the crystal structure of dimeric diphenyl antimony (III) dime-thyldithiophosphinate, [Ph2SbS2PMe2]2- Polyhedron 1996. 15. 4573. 

Decabromodiphenyl oxide - bro-(i)mo-(i) di- fe-n l ak- Sld (deca-bromodiphenyl either) n. Diphenyl ether in, which all ten phenyl hydrogens have been replaced by bromine, containing 83% bromine. The commercial product, a free-flowing white powder, is much used as a flame retardant in high-impact polystyrene and structural foam, usually with synergistic antimony oxide. Typical would be 12% decabromodiphenyl oxide and 4% antimony oxide in the resin See image). 

Decabromodiphenyl Etherf 1163-19-5]. This is the second largest bromi-nated flame retardant, and is used in HIPS, textile backcoating, and in polyoleflns, generally together with antimony oxide. It is made, as are the other members of this series, by bromination of diphenyl ether and is commercially available by Albemarle as SAYTEX 102, Great Lakes Chemical as DE-83, and Dead Sea Bromine (DSBG) as FR-1210. In view of the large volume and multiple producers, it is priced favorably. The structure is as follows ...
