【 摘 要 】

A tetranuclear iron grid-type spin crossover complex, [Fe-4(II)(HL)(4)](BF4)(4)center dot 6H(2)O (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 Mossbauer spectra.
