摘要：
Iron(II) complexes [Fe(II)(dppFc)(2)](X)(2)center dot n(solv.) (1(X)(2)center dot n(solv.)) (dppFc = 1-ferrocenyl-2-{(2,6-bis(pyrazol-yl) pyridyl)-ethylene}, X = I(3)(-), BPh(4)(-), [Ni(mnt)(2)]) were prepared and their magnetic properties were studied. The central iron(II) ion in 1(X)(2)center dot n(solv.) was coordinated by two tridentate ligands, which have redox active ferrocenyl groups. Magnetic susceptibility measurements revealed that the central iron(II) ions in 1(2+) and in ferrocenes are in high- and low-spin states, respectively, in the temperature range measured.
