Elusive Co₂O₃: A Combined Experimental and Theoretical Study.

The main point in the overall studies involving experimental and computational results is that Co 2 O 3 with 3d 6 Co 3+ ions with S = 0 neither stabilizes in corundum nor in cubic form, while other systems with S = 0 (Y 3+ : 4d 0 and Al 3+ : valence orbitals are 3s and 3p) stabilize in cubic and corundum crystal respectively, which is highly significant. 3 Conclusions Based on the studies, it seems apparent that Co 2 O 3 itself does not exist but forms stable solid solutions with Y 2 O 3 and Lu 2 O 3 in the cubic bixbyite structure.
