Rapid electronic relaxation phenomenon in a 2T ? 6A spin-equilibrium system

The magnetic susceptibilities, M?ssbauer spectra, and electron paramagnetic resonance (EPR) spectra of [Fe(acen)(dpp)](BPh4), [Fe(acen)(pic)2](BPh4), and [Fe(acen)(lut)2](BPh4) have been measured in the solid state [acen = N,N′-bis(1-methyl-3-oxobutylidene)ethylenediamine, dpp = 1,3-di-4-pyridylpropane, pic = 4-methylpyridine, lut - 3,4-dimethylpyridine, and BPh4 = tetraphenylborate ion]. The variable-temperature magnetic susceptibility for these complexes has been interpreted by the spin-crossover phenomenon between 6A and 2T states. The EPR parameters for the T state have been used to determine the energy levels of three Kramers doublets. The temperature dependence of the M?ssbauer spectra for [Fe(acen)(dpp)](BPh4) and [Fe(acen)(pic)2](BPh4) has proved the existence of rapid electronic relaxation between two spin states in comparison with the M?ssbauer lifetime of 0.97 × 10-7 s. The separation energies between the two spin states have been estimated to be 330 and 339 cm-1 for [Fe(acen)(dpp)](BPh4) and [Fe(acen)(pic)2](BPh4), respectively, by the theoretical calculation of the temperature dependence of the quadrupole splittings.
