The sketch map of Cr₂MoO₆ crystal structure. The black balls, blue balls, and red balls represent Cr atoms, Mo atoms, and O atoms, respectively. The Cr bilayers are separated by a Mo layer. The O atoms connecting inter-bilayer Cr atoms are marked as O1, and the O atoms connecting intra-bilayer Cr atoms are marked as O2. The labeled Mo1 and Mo2 atoms are equivalent.
