摘　　要：A cyanide-bridged Fei^III2Coll double zigzag chain, { [Fen1（bipy）（CN）4]2Con（btab）2}n [bipy=2,2＇-bipyridine, btab=4,4＇-（1,3-phen- ylene）-bis-4H-1,2,4-triazole] （1）, was obtained with tetracyanometalate precursors and Con ions. The chains were further linked by the ditopic btab ligands to a layer. Magnetic property studies demonstrate that 1 shows both metamagnetism with a critical field He=400 Oe and single-chain magnet behavior.A cyanide-bridged FeⅢ2CoⅡ double zigzag chain, {[FeⅢ（bipy）（CN）4]2Co～Ⅱ（btab）2}n [bipy=2,2′-bipyridine, btab=4,4′-（1,3-phenylene）-bis-4H-1,2,4-triazole]（1）, was obtained with tetracyanometalate precursors and CoII ions. The chains were further linked by the ditopic btab ligands to a layer. Magnetic property studies demonstrate that 1 shows both metamagnetism with a critical field Hc=400 Oe and single-chain magnet behavior.
