Synthesis, structure and magnetism of new bimetallic assemblies, [Ni(chxn)(2)](3)[M(CN)(6)](2)center dot 2H(2)O (chxn=1,2-trans-cyclohexane-diamine; M-III= Fe, Co)
A new type of cyanide-bridged bimetallic assemblies, [Ni(chxn)(2)](3)[M(CN)(6)](2).2H(2)O (chxn = 1,2-trans-cyclohexanediamine; M3+-Fe (1), Co (2)), have been prepared. The X-ray crystallography for the assemblies has proved a 2-D network comprised of M6Ni6 dodecagon units extended by M-CN-Ni linkage. Compound 1 shows a ferromagnetic spin-exchange interaction between the adjacent Fe(III) and Ni(II) ions through cyanide bridge and a long-range magnetic ordering below 13.1 K.
