Tin(IV) bromide
（重定向自Stannic bromide）
Tin(IV) bromide is the chemical compound SnBr4. It is a colourless low melting solid. SnBr4 can be prepared by reaction of the elements at normal temperatures:
In aqueous solution Sn(H2O)6 is the principal ionic species amongst a range of 6 coordinate ions with from 0-6 bromide ligands (e.g. Sn(H2O)6, SnBr(H2O)5) In basic solution the Sn(OH)6 ion is present.
SnBr4 forms 1:1 and 1:2 complexes with ligands, e.g. with trimethylphosphine the following can be produced, SnBr4.P(CH3)3 and SnBr4.2P(CH3)3.
SnBr4 crystallises in a monoclinic form with molecular SnBr4 units that have distorted tetrahedral geometry.
