The correlated anion order in the oxynitride perovskite NdVO 2 N, where disordered zig-zag VN chains segregate into planes within a pseudo-cubic lattice, is similar to that in materials such as SrTaO 2 N containing d 0 transition metal cations. However, NdVO 2 N has 3d 1 V 4+ cations and the 3d-elec...

Zusammenfassung:The correlated anion order in the oxynitride perovskite NdVO 2 N, where disordered zig-zag VN chains segregate into planes within a pseudo-cubic lattice, is similar to that in materials such as SrTaO 2 N containing d 0 transition metal cations. However, NdVO 2 N has 3d 1 V 4+ cations and the 3d-electrons are itinerant, showing that the anion chain order in oxynitride perovskites is robust to electron-doping. The structure of the compound NdVO2N contains layers of spontaneously segregated cis -nitride chains, like those in d 0 oxynitride perovskites. NdVO2N has 3d 1 V 4+ cations and the 3d-electrons are itinerant, showing that the anion chain order in oxynitride perovskites is robust to electron-doping.
