Tin(II) iodide, also known as stannous iodide, is the inorganic compound with the formula SnI2. It is a red-orange solid. It reacts with iodine to give tin(IV) iodide.[1]
Tin(II) iodide can be synthesised by heating metallic tin with a mixture iodine in 2 M hydrochloric acid.[2][1]
- Sn + I2 → SnI2
Structure
It crystallizes in a unique motif. According to X-ray crystallography, some Sn(II) centers are bound to six iodide ligands others Sn(II) sites are distorted.[3]
