Preparation of iron(IV) nitridoferrate Ca4FeN4 through azide-mediated oxidation under high-pressure conditions
Abstract
High-valent metal nitrides are difficult to stabilise due to the high thermodynamic stability and chemical inertness of N2. Here, the authors employ a large volume press to prepare an iron(IV) nitridoferrate Ca4FeIVN4 from Fe2N and Ca3N2 via azide-mediated oxidation under high pressure conditions.
