DOIAbstract
A tetranuclear iron grid-type spin crossover complex, [FeII4(HL)4](BF4)4·6H2O (1) (H2L = 2-(4-hydroxyphenyl)-4,5-bis{6-(3,5-dimethylpyrazol-1-yl)pyrid-2- yl}-1H-imidazole), was synthesized. Magnetic susceptibility measurements revealed that 1 shows gradual spin crossover behavior above 200 K. The electronic states of the compound were elucidated by Mössbauer spectra
