The recently obtained Mössbauer and EPR parameters of the Fe 4 S 4  3+  polymetallic center in the High Potential Iron-Sulfur Protein (HiPIP) II from E. halophila have been reproduced with models based on pure Heisenberg exchange. The role of double exchange versus ./-inequivalence is discussed. An evaluation of the upper limit of the double exchange parameter in the Fe 4 S 4  3+  bimetallic center is also presented. The present calculations shed further light on the electronic structure of the Fe 4 S 4  3+  center.
