30. 3Cl. The minor change does not affect the present discussion and conclusion made in the text
31. g conduction bands with increasing temperature [11]. However, the pyramidally coordinated Co ion sees a weak CF in the LCOs and the Co 3d electrons have a decreasing pdσ hybridization both due to the apical-oxygen deficiency and the strong base corrugation. The mechanism of forming the LS (IS) state by a strong CF (a strong pda hybridization) seems ineffective in the LCOs, and therefore the HS state is preferable instead
32. 2g near degeneracy is lifted even by a weak Jahn-Teller distortion as discussed in the text
