摘要: Unrestricted density functional theory calculations have been conducted on two diiron(II) synthetic model compounds. Calculations employed the BPW91 and BOP functionals with both high-spin broken symmetry low-spin representations of weakly coupled irons. Comparison calculated crystallographic structures is made, good agreement found spin representations. Raman spectral data are available for diiron(III) product reaction O2 to form a bridged peroxide. Calculated harmonic frequencies confirm experimental assignments. Small geometry differences between high results seen in bond lengths, angles, frequencies, densities associated oxo peroxo bridges oxidation products. © 2009 Wiley Periodicals, Inc.
