Neptunium tetrachloride is a binary inorganic compound of neptunium metal and iodine with the chemical formula NpCl4.[1][2]
Synthesis
The compound can be prepared from the reaction of neptunium mononidride with HCl:[3]
- 2NpN + 8HCl → N2 + 4H2 + 2NpCl4
Also, reaction of neptunium sulphide with HCl:
- Np2S3 + 8HCl → 2NpCl4 + 3H2S + H2
Other reactions are also used.[4]
Physical properties
NpCl4 crystallizes in tetragonal space group I41/amd.[5]
Chemical properties
The compound reacts with ammonia:[3]
- 6NpCl4 + 2HN3 → 6NpCl3 + 6HCl + N2
