A cyanide-bridged Fe~Ⅲ_2Co~Ⅱ double zigzag chain, {[Fe~Ⅲ(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.
