Abstract: | A novel cyan‐bridged macrocyclic nickel complex {NiL1}{Fe(bipy)(CN)4}]2·5H2O 1 (L1 = 3,10‐dimethyl‐1,3,6,8,10,12‐hexaazacyclotetradecane, bipy = 2,2‐bipyridine) was synthesized and structurally characterized. 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. |
