![]() uranium nitride
• Formula as commonly written: U3N2 • Hill system formula: N2U3 • CAS registry number: [12033-85-1] • Formula weight: 742.1 • Class: nitride Synonyms • uranium nitride • uranium(II) nitride • diuranium trinitride Physical properties • Colour: dark grey • Appearance: crystalline solid • Melting point: 900°C (decomposes to UN) • Boiling point: • Density: Element analysis and oxidation numbers For each compound, and where possible, a formal oxidation number for each element is given, but the usefulness of this number is limited, especially so for p-block elements in particular. Based upon that oxidation number, an electronic configuration is also given but note that for more exotic compounds you should view this as a guide only. Element % Formal oxidation state Formal electronic configuration N 3.77 -3 [He].2s2.2p6 U 96.23 2 [Rn].5f4 Synthesis Not available Isotope pattern What follows is the calculated isotope pattern for the U3N2 unit with the most intense ion set to 100%.
