摘要 Some new tris(2-pyridylimine) complexes of iron(II) such as FeL3X2 (L=substituted imine ligand, 2-py-CR1=NR2, where R1 or R2=H, CH3(Me) and C6H5(pH), X=ClO¯.. a or NSC¯, have been synthesized and their electronic structures in the solid state examined by magnetic measurement and 57Fe Mossbauer spectroscopic studies. All the perchlorate complexes FeL3(ClO4)2 are low-spin electronic ground state of Fe(II). The dithiocyanato-complexes, FeL3(NCS)2; the spin states of Fe(II) are dependent on substituent R1 and R2. The two complexes Fe(2-py-CH=NH)3(NCS)2 and Fe(2-py-CPh=NH)3(NCS)2 are spin-intermediate (S=1) and Fe(2-py-CH=NPh)3(NCS)2 shows a thermally inducing spin transition of 5T..1A, whereas the other derivatives remain a low-spin (S=0, 1A1) ground state of Fe(II) at there temperatures of 298,202 and 78K.
