The recently obtained Mössbauer and EPR parameters of the Fe4S43+ 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 Fe4S43+ bimetallic center is also presented. The present calculations shed further light on the electronic structure of the Fe4S43+ center.
