properties

Crystal structure of tin (IV) bromide

Tin (IV) bromide is a colorless solid that smokes in air and is easily soluble in water. It has a monoclinic crystal structure with the space group P 2 ₁ / c (space group no. 14) , a = 1037.1 pm, b = 700.6 pm, c = 1047.0 pm, β = 102.56 °, Z = 4. Template: room group / 14

use

Tin (IV) bromide as the starting material for tin (IV) oxide by laser-assisted chemical vapor deposition (engl. Laser-assisted CVD ) were used and thereby has a higher efficiency than other starting materials such as dibutyltin diacetate . It is also used to separate minerals.
