Abstract

Temperature-dependent Mossbauer spectroscopy and variable temperature Fourier transform infrared techniques were employed to follow the spin conversion of Fe(BPTN)(NCS)₂ and Fe(TPA)(NCS)₂ complexes. The hyperfine interaction parameters and Debye-Waller factors were determined using the Mossbauer effect. The complexes show gradual HS to or from LS transition in the temperature range 4.2-300 K. The lattice dynamical properties at the metal sites in the ¹A₁ state were observed to be significantly different from those in the ⁵T₂ configuration. It has been demonstrated that detailed f-factor measurements may be essential for accurate estimation of the spin-conversion function of such complexes.
