摘要：

The synthesis, structural and magnetic properties of the 2-D bimetallic complex [NiL3](3)[Fe(CN)(6)](2). 8H(2)O (L-3=3,10-dihydroxyethyl-1,3,6,8,10,12-hexaazacyclotetradecane) are presented. The structure consists of cyano-bridged neutral honeycomb-like layers. Each hexacyanoferrate(III) ion connects three nickel(II) ions using three cis CN- groups and the remaining CN- groups are terminal. The bridging cyanide ligands coordinate to the nickel ion in a trans fashion. Magnetic studies showed that the complex displays a metamagnetic behaviour arising from intralayer ferromagnetic coupling and interlayer antiferromagnetic interactions. A long-range magnetic ordering at T-c=6.0 K was observed. In addition, the ionic complex [NiL4](3)[Fe(CN)(6)](2). 6H(2)O (L-4=8-methyl-1,3,6,8,10,13,15-heptaazatricyclo[13.1.1.1(13,15)]octadecane) showing the absence of cyano bridging, is reported.
