Fig. 1: Synthesis and crystal structure of CCNOO.
From: High-temperature ferrimagnetic order triggered metal-to-insulator transition in CaCu3Ni2Os2O12
a Schematic crystal structure of both A- and B-site ordered quadruple perovskite oxide AA′3B2B′2O12. The corner-sharing B/B′O6 octahedra and A′O4 planar squares are shown. b SXRD pattern and Rietveld refinement results for CCNOO at room temperature. The black ticks indicate the allowed Bragg reflections with space group Pn-3.
