Abstract
The energy states of tetrameric iron clusters with d6-d6-d6-d5 and d5-d5-d5-d6 electronic configurations, which form the metal frameworks of the [Fe4S4]+ and [Fe4S4]3+ iron-sulfur proteins, are calculated using a general approach. It is revealed that the structural distortions of these systems significantly affect the composition of the magnetic states. The effect of the isotropic Heisenberg exchange is considered.
