Anion-ordered chains in a d1 perovskite oxynitride: NdVO2NElectronic supplementary information (ESI) available: Details of the synthesis, analysis, structural characterisations, and property measurements. See DOI: 10.1039/c3cc38736d
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...

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

N has 3d

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

oxynitride perovskites. NdVO2N has 3d

V
4+
cations and the 3d-electrons are itinerant, showing that the anion chain order in oxynitride perovskites is robust to electron-doping. |
