The spin states of iron (II) in FeL2(NCS)2 produced from the thermal decomposition of Fel3(NCS)2 (L=2-py-CR1=NR2, R1 or R2=H, Me(CH3), Ph) under nitrogen atmosphere are investigated by means of mossbauer spectroscopy and magnetic measurements. It was found that the spin states of iron (II) in substitutited bis (2-pyridylimine) iron (II) thiocyanate are included: intermediate-spin (3T1, S=1), mixed-spin of 3T2(S=2)+2T1 and spin incomplete transition of 5T2…3T1.
