Stannane or tin hydride is an inorganic compound with the chemical formula SnH<sub>4</sub>. It is a colourless gas that ignites on contact with air. SnH<sub>4</sub> is a heavy analogue of methane but much less robust. In contrast to this rarely used species, stannane also refers to a large collection of organotin compounds.
Stannane can be prepared by the reaction of and lithium aluminium hydride according to the following idealized equation:
Stannane decomposes slowly at room temperature to give metallic tin and hydrogen.
Organotin hydrides are more stable, e.g. triphenyltin hydride, also known as triphenylstannane.
The volatility of stannane is potentially relevant to production of microchips.
