Tin(IV) bromide is the

chemical compound A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one elemen ...

SnBr₄. It is a colourless low melting solid. SnBr₄ can be prepared by reaction of the elements at normal temperatures: :Sn + 2Br₂ → SnBr₄ In

aqueous solution An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. For example, a solution of table salt, or sodium chloride (NaCl), in water would be ...

Sn(H₂O)₆⁴⁺ is the principal ionic species amongst a range of 6 coordinate ions with from 0-6 bromide ligands (e.g. Sn(H₂O)₆⁴⁺, SnBr(H₂O)₅³⁺); in basic solution the Sn(OH)₆²⁻ ion is present. SnBr₄ forms 1:1 and 1:2 complexes with

ligand In coordination chemistry, a ligand is an ion or molecule (functional group) that binds to a central metal atom to form a coordination complex. The bonding with the metal generally involves formal donation of one or more of the ligand's electro ...

trimethylphosphine Trimethylphosphine is a neutral organophosphorus compound with the formula P(CH3)3, commonly abbreviated as PMe3. This colorless liquid has a strongly unpleasant odor, characteristic of alkylphosphines. The compound is a common ligand in coordin ...

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, with mean Sn-Br bond lengths of 242.3 pm.
