Abstract: | The electronic structures of three dinuclear iron complexes were determined with the DFT method. The complexes contain a {Fe(NO)2}9 unit and thiolate, nitrosyl, carbonyl and amine ligands at the second iron atom. The two iron atoms are bridged by thiolate ligands. In the lowest energy states of these complexes, the iron atoms possess spin S = 1, 3/2 or 5/2, depending on the coordinated ligands and their mutual arrangement. Nitrosyl is coordinated as NO− antiferromagnetically coupled to iron, and the two iron units are antiferromagnetically coupled to each other. |
