A new bimetallic assembly magnet [{Ni(tn)(sub 2)}(sub 5){Fe(super III)(CN)(sub 6)}(sub 3)](sub n)(ClO4)(sub n).2.5nH(sub 2)O (tn = trimethylenediamine) with a novel 3-D tunnel structure

A novel molecular-based magnet of three-dimensional (3-D) cyanide-bridged bimetallic assembly, [{Ni(tn)(sub 2)}(sub 5){Fe(super III)(CN)(sub 6)}(sub 3)](sub n)(ClO4)(sub n).2.5nH(sub 2)O where tn = trimethylenediamine, was synthesized and structurally characterized. The cryomagnetic properties show that 3-D magnetic ordering occurs over the lattice below the Curie temperature around 10 K.
