Tin (IV ) bromide is an inorganic chemical compound of the tin from the group consisting of bromides.

Production and representation

Tin (IV ) bromide tetrahydrate, can be obtained by reaction of tin ( IV) oxide with hydrobromic acid. The anhydrate can be obtained by reaction of the elements.

Properties

Tin ( IV ) bromide is a colorless, fuming in air solid which is readily soluble in water. It has a monoclinic crystal structure with space group P21 / c ( a = 1037.1 pm, b = 700.6 pm, c = 1047.0 pm, β = 102.56 °, Z = 4).

Use

Tin (IV ) bromide is used as the starting material for tin ( IV) oxide by laser-assisted chemical vapor deposition (English laser -assisted CVD) and thereby has a higher efficiency than other starting materials such as dibutyl tin diacetate. It is also used for separation of minerals.
