抜粋

The new ternary nitrides SrZrN2 and SrHfN2 have been synthesized by the solid state reactions of Sr2N with ZrN and HfN and characterized by powder X-ray diffraction. Both nitrides form structures in the hexagonal space group A3̄m (SrZrN2, a = 3.37302(5) Å, c = 17.6756(3) Å, Z = 3; SrHfN2, a = 3.34481(3) Å, c= 17.6779(2) Å, Z = 3) and are isostructural with α-NaFeO2. The structures are constructed of alternating layers of strontium-nitrogen edge-sharing octahedra and either zirconium-nitrogen or hafnium-nitrogen edge-sharing octahedra stacked along the c axis. Alternatively, Sr2+ can be regarded as occupying octahedral holes between Zr(Hf)N2 octahedral layers. The title nitrides are essentially diamagnetic at room temperature, consistent with the chemical composition. These compounds are the first alkaline earth ternary nitrides observed to have the α-NaFeO2 layered structure. 1 The University of Nottingham 2 The University of Birmingham.
