Slow Magnetic Relaxation in a Mononuclear 8‐Coordinate Fe(II) Compound Bearing the Phenanthroline‐Amide Ligand

A mononuclear 8‐coordinate Fe(II) compound, [Fe II ( L 1 ) 2 ](CF 3 SO 3 ) 2 ( 1 ), was prepared from the reaction of a neutral tetradentate ligand ( L 1 = N 2 , N 9 ‐dibutyl‐1,10‐phenanthroline‐2,9‐dicarboxamide) and hydrated Fe(CF 3 SO 3 ) 2 in MeOH. 1 could be considered as an ‘ideal’ 8‐coordinat...

Description
Summary:A mononuclear 8‐coordinate Fe(II) compound, [Fe II ( L 1 ) 2 ](CF 3 SO 3 ) 2 ( 1 ), was prepared from the reaction of a neutral tetradentate ligand ( L 1 = N 2 , N 9 ‐dibutyl‐1,10‐phenanthroline‐2,9‐dicarboxamide) and hydrated Fe(CF 3 SO 3 ) 2 in MeOH. 1 could be considered as an ‘ideal’ 8‐coordinate Fe(II) compound as compared with the previously reported Fe(II) analogs, because all the terminal Fe−O bond lengths are in the normal range. The magnetic properties investigation shows that 1 exhibit field‐induced slow magnetic relaxation behavior.
