摘要
(Figure Presented) Polinuclear Fe II Clusters: A new family of {Fe 5} cluster compounds formulated with [{Fe II(μ-bpt) 3} 2Fe 3 II(μ3O)]X 2 have been synthesised from the solvothermal reactions of 4-amino-3,5-bis(pyridine-2- yl)-1,2,4-triazole with-ferrous salts. The spin states of the two apical iron(II) ions in the cationic pentanuclear (Fe 5} clusters can be tuned to give the high-spin states by the [Fe 2OCl 6] 2- anion and the low-spin states by SCN -/ClO 4 -/I - (see scheme). © 2010 Wiley-VCH Verlag GmbH & Co.
