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).
