Titanium (III ) bromide is an inorganic chemical compound of titanium selected from the group of the bromides.

Production and representation

Titanium (III ) bromide, by reaction of titanium (IV ) bromide with hydrogen

Or be obtained directly from the elements.

The hexahydrate can be represented in hydrochloric acid solution, and this with hydrobromic acid precipitates on saturating the solution by reduction of titanium (IV ) bromide.

Properties

Titanium (III ) bromide is present as blue-black, blue-green in phantom crystals, which are soluble in water and at 550 ° C in titanium (II ) bromide and titanium ( IV ) bromide decompose. Titanium (III ) bromide occurs in two different crystal structures, wherein the alpha- form of trigonal of titanium ( III) chloride with the space group R3 ( a = 640 pm b = 1870 pm ) corresponds. This also existing hexahydrate is a reddish -violet crystalline solid that melts at 115 ° C and decomposes at 400 ° C. It is soluble in water, methanol, ethanol and acetone, but insoluble in carbon tetrachloride and benzene.
