Abstract

The local structure around iron atom is important to show spin-crossover phenomenon in the assembled Fe(II) complexes. In the present study, the low symmetry bridging ligand, 2,6-diethyl-bis(4-pyridyl)benzene (2,6-debpb) (A-B type ligand) was synthesized. And the assembled Fe(II) complexes, [Fe(NCX)2(2,6-debpb)2]n (X = S, Se, BH3), were synthesized. [Fe(NCS)2(2,6-debpb)2]n showed the temperature independent high-spin state, while small amount of low-spin state was observed in 57Fe Mössbauer spectrum at 78 K for [Fe(NCX)2(2,6-debpb)2]n (X = Se, BH3). Magnetic susceptibility measurement supported the 57Fe Mössbauer results. X-ray structural analysis for [Fe(NCBH3)2(2,6-debpb)2]n revealed that the local structure around iron atom is distorted, disturbing the approach of the ligand to iron atom not to show complete spin-crossover phenomenon. The local structure is FeA2B2 type and there was no disorder in the bridging ligand.
