A cyanide-bridged FeIII 2CoII double zigzag chain, {[FeIII(bipy)(CN)4]2CoII(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 H c=400 Oe and single-chain magnet behavior.
