A serials of sandwich-like trinuclear and one-dimensional chain cyanide-bridged iron(III)-copper(II) complexes: Syntheses, crystal structures and magnetic properties

A serials of five new cyanide-bridged Fe(III)-Cu(II) complexes with different structure types have been synthesized and characterized by elemental analysis, IR spectroscopy and X-ray structure determination. Investigation over magnetic properties of the whole serials of complexes reveals the antiferromagnetic magnetic coupling between the neighboring cyanide-bridged Fe(III) and Cu(II) ions in two trinuclear complexes and the ferromagnetic coupling in the additional trinuclear complex and the other two 1D complexes, respectively.203
