Neptunium(IV) phosphide is a binary inorganic compound of neptunium metal and phosphorus with the chemical formula Np3P4. [1]
Neptunium(IV) phosphide can be formed from the fusion of stoichiometric amounts of neptunium and red phosphorus in an evacuated and sealed quartz tube at 750 °C: [2] [3]
Neptunium(IV) phosphide forms black crystals of cubic crystal system, spatial group I 43d. Isostructural with Th3P4. [4]
It does not dissolve in water.

Curium hydroxideCm(OH)3 is a radioactive compound first discovered in measurable quantities in 1947. It is composed of a single curium atom and three hydroxy groups. It was the first curium compound ever isolated.
Curium(III) fluoride or curium trifluoride is the chemical compound composed of curium and fluorine with the formula CmF3. It is a white, nearly insoluble salt that has the same crystal structure as LaF3. It precipitates as a hydrate when fluoride ions are added to a weakly acidic Cm(III) solution; alternatively it can be synthesized by reacting hydrofluoric acid with Cm(OH)3. The anhydrous form is then obtained by desiccation or by treatment with hydrogen fluoride gas.
