Four iron complexes {[PhN(CH 2 ) 2 NH(SiMe 3 )] 4 FeLi · Et 2 O ( 1 ), [PhN(CH 2 ) 3 NSiMe 3 ] 2 FeLi(Et 2 O) ( 2 ), [PhN(CH 2 ) 2 NCH(Ph)NSiMe 3 ] 2 FeLi(Et 2 O) 2 ( 3 ), and [PhN(CH 2 ) 3 NCH(Ph)NSiMe 3 ] 2 FeLi(Et 2 O) 2 ( 4 )} with polydentate nitrogen ligands were synthesized and structurally characterized by X‐ray crystallography. The X‐ray structures of complexes 1 – 4 show that they crystallize in three different systems. The magnetic properties of 1 – 4 were investigated. The magnetization trends of magnetic field intensity show the curves of Type‐ S , illustrating those complexes 1 – 4 are superparamagnetic.
