Neptunium tetrachloride is a binary inorganic compound of neptunium metal and chlorine with the chemical formula NpCl4. [1] [2]
The compound can be prepared from the reaction of neptunium mononidride with HCl: [3]
Also, reaction of neptunium sulfide with HCl:
Reaction of carbon tetrachloride with neptunium(IV) oxide or NpO2. Neptunium tetrachloride is formed as a yellow sublimate. [4]
Other reactions are also used. [5]
NpCl4 crystallizes in tetragonal crystal system of space group I4/amd. [6]
The compound reacts with ammonia to produce neptunium trichloride: [3]
Neptunium tetrachloride can be reduced to neptunium trichloride by hydrogen at 450 °C.
