Stannane /ˈstæneɪn/ or tin hydride is an inorganic compound with the chemical formula SnH4. It is a colourless gas and the tin analogue of methane. Stannane can be prepared by the reaction of SnCl4 and Li[AlH4].[1]
- SnCl4 + Li[AlH4] → SnH4 + LiCl + AlCl3
Stannane decomposes slowly at room temperature to give metallic tin and hydrogen and ignites on contact with air.[1]
Variants of stannane can be found as a highly toxic, gaseous, inorganic metal hydrides and group 14 hydrides.
