Abstract

For the first time, the unusual O-coordination mode of nitrosamines to Fe(III) heme models is described through ab initio methods in the bis(dimethylnitrosamine-DMNA)(meso-tetraphenylporphyrinate)iron(III) and bis(DMNA)(porphinate)iron(III) cations. On page 508, Ezequiel F. V. Leitão, Elizete Ventura, Otávio L. de Santana, and Silmar A. do Monte show that the DMNA ligand can be classified as a weak field ligand. The cover shows the occupancy diagram for 3d orbitals of the ground spin state (sextet) of the smaller heme model cation.
