    • 5)Fe relative to the bridging ligand were considered. Even though our conformational study was not exhaustive, each system always reorganized itself into to a unique geometry regardless of the starting geometry considered. It has to be noted that NMR indicates the fluxionality of the metallic end groups in solution.
