General Description
Antimony tribromide is the yellow crystalline solid dissolved in hydrobromic acid. Antimony tribromide is decomposed by water giving an antimony oxide and hydrobromic acid. Antimony tribromide is corrosive to metals and tissue. Antimony tribromide is used to make other antimony compounds, in chemical analysis, and in dyeing.
Air & Water Reactions
Water slowly hydrolyzes antimony tribromide to form antimony (III) oxide and hydrobromic acid. The dry powdered oxide ignites on heating in air [Mellor Vol. 9 425.1939].
Reactivity Profile
Acidic salts, such as ANTIMONY TRIBROMIDE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
Hazard
Toxic.
Health Hazard
TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.
Safety Profile
A poison. Corrosive to
skin, eyes, and mucous membranes.
Reaction with water liberates HBr and
antimony trioxide. Can cause severe burns.

Potential Exposure
Antimony tribromide is used to make
antimony salts; in dyeing, and analytical chemistry.

Incompatibilities
Contact with water reacts, liberating
antimony trioxide and hydrogen bromide. Dry trioxide
material may explode if heated air. Heat forms toxic bromides.
Antimony tribromide attacks various metals.
Waste Disposal
Encapsulate and bury at an
approved chemical landfill. Unacceptable for disposal at
sewage treatment plants. Consult with environmental regulatory
agencies for guidance on acceptable disposal practices.
Generators of waste containing this contaminant
(≥100 kg/mo) must conform with EPA regulations governing
storage, transportation, treatment, and waste disposal.
Check Digit Verification of cas no
The CAS Registry Mumber 7789-61-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7789-61:
(6*7)+(5*7)+(4*8)+(3*9)+(2*6)+(1*1)=149
149 % 10 = 9
So 7789-61-9 is a valid CAS Registry Number.

Bromide mediated oxidation of antimony(III) by cerium(IV) in aqueous sulphuric acid medium

, p. 1579 - 1584 (2008/03/27)
The micro amount (10-3 mol dm-3) of bromide mediated oxidation of antimony(III) by cerium(IV) in an aqueous sulphuric acid medium has been studied spectrophotometrically at 25°C and I = 3.10 mol dm -3. In the presence of bromide, one mole of antimony(III) requires two moles of cerium(IV). The reaction is first order with respect to [cerium(IV)] and [bromide], whereas the order with respect to [antimony(III)] is less than unity. Increase in [sulphuric acid] accelerates the reaction rate. The order with respect to [H+ ion] is less than unity. Added products, cerium(III) and antimony(V) do not have any significant effect on the rate of reaction. The active species of oxidant is identified as H 3Ce(SO4)4-, whereas that of reductant as SbBr2+. The possible reaction mechanism is proposed and the activation parameters determined and discussed.
SOME CO-ORDINATION COMPOUNDS OF TaCl3S AND TaBr3S. X-RAY CRYSTAL STRUCTURE OF

The reaction of TaX5 (X = Br or Cl) with Sb2S3 (molar ratio 3:1) led to the formation of TaX3S.With L these species form complexes of formulation TaX3S*2L (L = dimethyl sulphide, tetrahydrothiophene, or MeCN) and TaX3S*L .The exact nature of the complexes was ascertained by a single-crystal X-ray study on TaCl3S*bpte.The crystals are monoclinic, space group P21/c, Z = 4 with a = 15.538(20), b = 7.352(8), c = 16.619(20) Angstroem, and β = 110.88(10) deg. 2 003 Independent reflections with I>4?(I) were used in the refinement and a R value of 0.062 obtained.The structural study showed that the metal atom was in a distorted octahedral environment with a terminal Ta=S bond , three metal-chlorine interactions , and two bonds to the sulphur atoms of the ligand.The bond trans to the terminal sulphur atom is longer than the bond that is cis .The Ta=S fragment has the expected influence on the three angles it forms at the metal with the three chlorine atoms that are bound cis to it, increasing the angles to ca. 100 deg.This is concomitant with a surprisingly small value of 86.5(2) deg for the angle S=Ta-S(cis).
