Molecules orbital depopulation

Spin complexes (Table 102). The spin-pairing has little effect on the average Cr—-N (porphyrin) distances since they are 2.033 A in Cr(TPP)-2PhMe (S = 2) and 2.027 A in Cr(TPP)(py)2 (5 = 1). However, the Cr—distances to the axial pyridine molecules (ca. 2.13 A) are considerably less than in isoelectronic high-spin manganese(III) complexes (ca. 2.4 A). This is attributed to the depopulation of the 3dz2 orbital on spin-pairing in the Cr complex. The alternative formulation of the Cr porphyrin complexes as porphyrin radical anion complexes is excluded by their visible spectra and oxidation-reduction behaviour. ... [Pg.2752]
