As part of a long-term study of dinuclear iron complexes with sulfur-rich coordination spheres and cofacial, sterically variable binding sites for molecules relevant to nitrogenase, the complex (AsPh4)2 [{Fe('apS4')}2] (5) was synthesized and completely characterized ['apS4'4- = 1,3-bis(2,3-dimercaptobenzamido)propane(4-)]. Complex 5 contains two cofacial [FeIII(S2C6H4R) 2]- units linked by [Fe-S-Fe] thiolate bridges and two peripheral propanediamide ligand backbones that are located on opposite sides of the molecular anion and prevent the complete separation of the two [FeS4] cores of 5 if the Fe-S-Fe bridges dissociate. No marked differences were found in the molecular parameters, spectroscopic, magnetic and electrochemical properties of the [Fe2S8] cores in the anion of 5 and the parent complex [{Fe(S2C6H4)2}2-.
