Despite several oxides with trivalent cobalt ions are known, the sesquioxide M2O3 with Co3+ ions remains elusive. Our attempts to prepare Co2O3 have failed. However, 50% of Co3+ ions could be substituted for Ln3+ ions in Ln2O3 (Ln = Y and Lu) with a cubic bixbyite structure where the Co3+ ions are in the intermediate-spin state. We have […] Bekijken
