    • Bonding in low-coordinate complexes : what, if anything, is special? 

      Tangen, Espen (Doctoral thesis; Doktorgradsavhandling, 2008-10-14)
      To contribute to the fundamental picture of the electronic structure of low-coordinate transition metal complexes, we have carried out a series of DFT studies on mono-imido and nitrosyl complexes for different metal ions (Mn<sup>II/III</sup>, Fe<sup>II/III/IV</sup>, Co<sup>II/III</sup>) and different systems of basal ligands. These studies reveal striking similarities of the electronic structure ...

    • High valent transition metal corrole and corrolazine complexes. The question of noninnocent ligands 

      Tangen, Espen (Master thesis; Mastergradsoppgave, 2003-06-06)
      To contribute to the fundamental picture of the electronic structure of high valent first row transition metal complexes, I have carried out a density functional study of two different macrocyclic ligand systems, corroles and corrolazines, with two different axial ligands, Ph and Cl and a number of different central ions, P(V), Cu(III), Mn(IV) and Fe(IV). DFT calculations on Fe(IV) and Mn(IV) corrole ...
