Abstract
The 2-D bimetallic complex [NiL]3[Fe(CN)6]2·9H2O (L represents 3,10-dimethyl-1,3,5,8,10,12-hexaazacyclotetradecane) has been prepared and its structure and magnetic properties studied. The structure consists of cyano-bridged neutral Ni3Fe2 units. 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 co-ordinate to the nickel ion in a trans fashion forming trans-NiL(NC)2 moieties. The nine water molecules are situated between the 2-D layer and hydrogen bonded to the terminal CN– ligands. Magnetic studies show that the complex displays a metamagnetic behaviour originating from intralayer ferromagnetic coupling and interlayer antiferromagnetic interaction. A long-range magnetic ordering over the lattice at Tc = 5 K is also observed.Keywords
