New synthetic routes to transition metal ternary nitrides and sulfides

Abstract

Three new synthetic methods for the synthesis of ternary transition metal nitrides and sulfides, respectively, are described. The reactions of metals dissolved in liquid zinc with nitrogen gas are shown to produce both binary and ternary nitrides. The reactions of the Group 2 binary nitrides with transition metal foils has led to the formation of ternary nitrides as single crystals. The new nitrides Ca 9Mo 2N 10 and Ca 33Mo 6N 33 are briefly discussed and the preparation and structure of the first nitride chloride containing chromium, Ba 4CrN 4Cl 2, is described. The method of separated reactants has been shown to give several Group 2–transition metal–sulfides also in the form of single crystals.
