The correlated anion order in the oxynitride perovskite NdVO₂N, where disordered zig-zag VN chains segregate into planes within a pseudo-cubic lattice, is similar to that in materials such as SrTaO₂N containing d⁰ transition metal cations. However, 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.
