| Abstract: | Three cyano-bridged Fe2Ni chain compounds were synthesized via the reaction of tetracyanometallate building block and pyridine ligands with different steric hindrance. Compounds {Fe(bpy)(CN)4]2Ni(bp)2]·2H2O}n (1) (bpy=2,2''-bipyridine; bp=4-phenylpyridine), {Fe(bpy)(CN)4]2Ni(papy)2]·H2O}n (2) (papy=4-(phenyldiazenyl)pyridine) and {Fe(bpy)(CN)4]2Ni(azp)]·4H2O}n (3) (azp=1,2-di(pyridin-4-yl)diazene) all show double-zigzag chain-like structures. Magnetic study indicates that compounds 1~3 all show intrachain ferromagnetic interactions. Alternating current susceptibility measurements demonstrated the single-chain magnet behavior of compound 1 with the relaxation energy barrier Ea/kB of 10.9 K. |
