Stannane/ˈstæneɪn/ ortin hydride is aninorganic compound with thechemical formulaSnH4. It is a colourless gas that ignites on contact with air. SnH4 is aheavy analogue ofmethane but much less robust. In contrast to this rarely used species, stannane also refers to a large collection oforganotin compounds.
Stannane can be prepared by the reaction ofSnCl4 andlithium aluminium hydride according to the following idealized equation:[1]
Stannane decomposes slowly at room temperature to give metallic tin and hydrogen.[1]
Organotin hydrides are more stable, e.g.triphenyltin hydride, also known as triphenylstannane.
The volatility of stannane is potentially relevant to production ofmicrochips.[2]
