The dihydrate has three coordinates as well, with one water on the tin and another water on the first. The main part of the molecule stacks into double layers in the crystal lattice, with the "second" water sandwiched between the layers.

They all consist of [SnCl 4 (H 2 O) 2] molecules together with varying amounts of water of crystallization. The additional water molecules link together the molecules of [SnCl 4 (H 2 O) 2] through hydrogen bonds. [3] Although the pentahydrate is the most common hydrate, lower hydrates have also been characterised. [4]
Insoluble in water and acetone. Soluble in dilute HCl, [4] methanol, and petroleum ether. [5] Forms crystal hydrates of the composition SnC 2 O 4 •n H 2 O, where n = 1 and 2. Decomposes on heating: +

Thionyl chloride is an inorganic compound with the chemical formula SOCl 2.It is a moderately volatile, colourless liquid with an unpleasant acrid odour.Thionyl chloride is primarily used as a chlorinating reagent, with approximately 45,000 tonnes (50,000 short tons) per year being produced during the early 1990s, [5] but is occasionally also used as a solvent.
The standard atomic weight takes into account the isotopic distribution of the element in a given sample (usually assumed to be "normal"). For example, water has a molar mass of 18.0153(3) g/mol, but individual water molecules have molecular masses which range between 18.010 564 6863 (15) Da (1 H 2 16 O) and 22.027 7364 (9) Da (2 H 2 18 O).
Water of crystallization is stabilized by electrostatic attractions, consequently hydrates are common for salts that contain +2 and +3 cations as well as −2 anions. In some cases, the majority of the weight of a compound arises from water. Glauber's salt, Na 2 SO 4 (H 2 O) 10, is a white crystalline solid with greater than 50% water by weight.
Zinc chloride is an inorganic chemical compound with the formula ZnCl 2 ·nH 2 O, with n ranging from 0 to 4.5, forming hydrates.Zinc chloride, anhydrous and its hydrates, are colorless or white crystalline solids, and are highly soluble in water.
