    • All calculations were carried out with the ADF program system, the VWN local exchange-correlation functional, PW91 gradient corrections, Slater-type triple-ζ plus polarization (TZP) basis sets, a fine mesh for numerical integration of matrix elements, and tight criteria for geometry optimizations. For additional technical details, the reader is referred to the program, available from: Scientific Computing and Modeling, Department of Theoretical Chemistry, Vrije Universiteit, 1081 HV Amsterdam, The Netherlands.

    • This is indeed what is expected. Dinitrosylheme intermediates are a suprising violation of this scenario; they strongly favor a cisoid orientation of the NO ligands: Conradie, J.; Wondimagegn, T.; Ghosh, A. J. Am. Chem. Soc. 2003, 125, 4968.

    • note
    • 2 exhibits significant paramagnetic shifts for the β-protons. However, as in the case Fe(porphyrinato)Cl complexes, we believe that these paramagnetic shifts result from very small unpaired spin populations at the β-carbons.
