抄録

Two-dimensional cyanide-bridged MIIINiII bimetallic assembies, [Ni(1,1-dmen)2]2[M(CN)6]tfs·3.5H 2O (M=Fe (1), Co (2); 1,1-dmen = 1,1-dimethylethylenediamine, tfs- = trifluoromethanesulfonate ion), have been prepared. Each compound forms a 2-D grid structure extended by the M-CN-Ni linkages. Compound 1 shows a ferromagnetic ordering below Tc of 8.9 K based on a ferromagnetic interaction between low-spin FeIII and high-spin NiII. MCD spectra for 1 show a strong Faraday ellipticity at ∼470 nm associated with the LMCT band of the Fe-CN bond. Its intensity increases with lowering temperature due to ferromagnetic ordering over the lattice. Compound 2 is paramagnetic and shows no remarkable Faraday effect.
