The Mössbauer, electronic, and IR spectroscopic data were invoked to carry out comparative analysis of the electronic structures and spectroscopic characteristics of the [Fe2CoO(CH3COO)6(3-Cl-Py)3] cluster (I) and [Fe3O(CH3COO)6(H2O) 3]+ cation (II) by the IEHM method. The formal electronic configuration of the cobalt ion in the ground state of the heteronuclear complex is dπ 4 dxy 1(dx2-y2)1 (dz2)1. The calculated Mössbauer parameters of the iron(III) ions in I and II agree with the experimental values δNa+ = 0.68, ΔEQ = 0.89 mm s-1 for I and δNa+ = 0.75, ΔEQ = 0.58 mm s-1 for II. The relationship between the compositions, electronic structures, and parameters of IR and electronic spectra of I and II is discussed. |
