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

Extraction and presentation

Titanium (II) bromide can be produced by thermal decomposition of titanium (III) bromide

or obtained directly from the elements.

properties

Titanium (II) bromide is in the form of black crystals that catch fire in moist air and decompose in water to form the titanium (III) salt, forming hydrogen . It has a trigonal crystal structure of the cadmium (II) iodide type ( polytype 2H) with the space group P 3 m 1 (space group no.164 ) and the lattice parameters a = 362.9, c = 649.2 pm.
