Anion-ordered chains in a d1 perovskite oxynitride: NdVO2N
DOI: 10.1039/C3CC38736D, CommunicationJudith Oro-Sole, Lucy Clark, William Bonin, J. Paul Attfield, Amparo Fuertes
The structure of the compound NdVO2N contains layers of spontaneously segregated cis-nitride chains, like those in d0 oxynitride perovskites. NdVO2N has 3d1 V4+ cations and the 3d-electrons are itinerant, showing that the anion chain order in oxynitride perovskites is robust to electron-doping.
