Abstract

A new oxynitride Ba3W2O6N2 has been synthesised from the ammonolysis of Ba3W2O9 . This compound crystallises in a hexagonal structure with a=5.993(2) and c=21.40(4) Å. Transmission electron microscopy (TEM) studies were carried out to elucidate the structure of this new compound. IR and Raman data are consistent with the C3v site symmetry of the (WO3N)3– unit. This compound is isostructural with Ba3V2O8 reported in the literature.
