Neptunium monocarbide is a binary compound of neptunium metal and carbon with the chemical formula NpC.[1][2]

Preparation

[edit]

Heating of freshly obtained neptunium hydride with carbon at 1400 °C:[3]

NpHx + C → NpC + (x/2)H2

Physical properties

[edit]

The compound forms black-grey crystals of cubic crystal system,[4] spatial group Fm3m.[5]
