A Novel Macrocyclic Nickel(Ⅱ) and Ferricyanide 1D Zigzag Chain: Synthesis, Crystal Structure, and Magnetic Properties

摘要

A novel cyan-bridged macrocyclic nickel complex [{NiL~1}{Fe(bipy)(CN)_4}]_2·5H_2O 1 (L~1 = 3,10-di-methyl-1,3,6,8,10,12-hexaazacyclotetradecane, bipy = 2,2-bipyridine) was synthesized and structurally char-acterized. The complex exhibits one-dimensional zigzag chain structures. Each ferrous(Ⅱ) ion connects two nickel(Ⅱ) ions using two trans CN~- groups, and the remaining CN~- groups are terminal. Magnetic measurement shows weak ferromagnetic interaction between the nearest Ni(Ⅱ) ions through the diamagnetic Fe(Ⅱ) ion.
