Anhydrous SnCl 2 is prepared by the action of dry hydrogen chloride gas on tin metal. The dihydrate is made by a similar reaction, using hydrochloric acid: Sn (s) + 2 HCl (aq) → SnCl 2 (aq) + H 2 (g) The water then carefully evaporated from the acidic solution to produce crystals of SnCl 2 ·2H 2 O.

In cis-SnCl 4 (H 2 O) 2 ·3H 2 O, the Sn-Cl bonds are 238.3 pm. [3] Although the pentahydrate is the most common hydrate, lower hydrates have also been characterised. [4] Aside from water, other Lewis bases form adducts with SnCl 4. These include ammonia and organophosphines. The ammonium salt of [SnCl 6] 2− is formed from ammonium chloride.
Trichlorostannate is the inorganic anion with the formula SnCl − 3. It is the chloride adduct of stannous chloride: SnCl 2 + Cl − → SnCl − 3. The trichlorostannate anion is pyramidal in shape, being similar to trichlorogermanate (GeCl − 3) and antimony trichloride. The anion can be isolated as quaternary ammonium salt and cesium salts ...
3 R 4 Sn + SnCl 4 → 4 R 3 SnCl R 4 Sn + SnCl 4 → 2 R 2 SnCl 2 R 4 Sn + 3 SnCl 4 → 4 RSnCl 3. A related method involves redistribution of tin halides with organoaluminium compounds. [2]: 45–47 In principle, alkyltin halides can be formed from direct insertion of the metal into the carbon-halogen bond.
Water (H 2 O) is an example of a bent molecule, as well as its analogues. The bond angle between the two hydrogen atoms is approximately 104.45°. [ 1 ] Nonlinear geometry is commonly observed for other triatomic molecules and ions containing only main group elements, prominent examples being nitrogen dioxide (NO 2 ), sulfur dichloride (SCl 2 ...
