- Source: Tin(IV) bromide
Tin(IV) bromide is the chemical compound SnBr4. It is a colourless low melting solid.
Structure
SnBr4 occurs in form of crystals. The compound crystallises in a monoclinic crystal system with molecular SnBr4 units that have distorted tetrahedral geometry, with mean Sn-Br bond lengths of 242.3 pm.
Preparation
SnBr4 can be prepared by reaction of the elements at standard temperature and pressure (STP):
Sn + 2Br2 → SnBr4
Dissolution in solvents
In aqueous solution SnBr4 dissolves to give a series of octahedral (six-ligated) bromo-aquo complexes. These include SnBr4(H2O)2 and cis- and trans-[SnBr2(H2O)4]2+.
Reactions
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.
