Is an inorganic compound.
Stannic sulfide Formula
It is SnS2. It is a hexagonal yellow flakes with a CdI2 crystalline structure. It is not very soluble but is soluble when mixed with hot alkali and aqua regia.
It is used to make gold paint.
The crystallization occurs in the form cadmium iodide, with Sn(IV), located in an "octahedral cavity" defined as six sulfide centres. It appears naturally as the rare mineral, montmorillonite. The bandgap is 2.2eV and it can be used for semiconductor materials.
SnS2 contains a hexagonal CdI2 n-type structure.
Tin disulfide SnS2
This is a layered metal-dihalide semiconductor that has a crystal and chemical structure similar to the molybdenum dihalide (MoS2). Sn is sandwiched by two Slayers, which have strong covalent ties, in each layer. Meanwhile, a monolayer is kept together with weak van der Waals bonds. If the van der Waals weak force is overcome through physical or chemical peeling then each layer will easily break.
SnS2 can be used to make photovoltaic solar panels, FETs and sensors.
Tin disulfide has an acidic sulfuric nature. It can be dissolved by aqua regia, hot alkali, concentrated hydrochloric, but not in water. It can be dissolved by ammonium-sulfide.

Stannic Sulfide SnS2 - Applications
Tin disulfide, or SnS2, is a van der Waals semiconductor material that has excellent photoelectric properties. Material is non-toxic, environment friendly, high in content, and easy to make. Tin sulfide has properties that are similar to semiconductors. These are commonly used for laboratory research and experimentation, but are also highly active on the market.
Tin disulfide has an n-type crystal structure of hexagonal CdI2 with a large bandgap (about 2.35eV). It is a semiconductor material that can be used to make solar cells and anodes for Lithium Chemicalbook subcells.
As tin diulfide is environmentally safe, has a similar bandgap to silicon and a high absorbance coefficient, it's a great choice for an absorber in solar cells. Experts from both home and abroad have been researching it for many years. This material can be used to manufacture and imitate gold. Use for paints etc.
Single-layer SnS2 can be made by stripping mechanically or with liquids from a tin-disulfide-single-crystal.
Tin disulfide can be used for liquid chemical exfoliation in order to produce SnS2 particles and nanosheets with as few as a couple of layers.
Tin disulfide exhibits high surface activity and sensitivity. SnS2 is also used as a single-layer, or multi-layer, ultra-thin SnS2 film, made of powder and bulk crystals. It has been used to make light emitters and gas sensors. Thermoelectric Photovoltaic, other fields, and energy-storage equipment such as lithium-ion cells.
Stannic Sulfide SnS2: Storage Conditions
