Abstract

Single molecule magnets and magnetic properties of advanced low-dimensional materials, especially for spintronic applications. They may be constructed from copper (II) ion and ditopic ligands, such as 2,2’-bipyridine and 4,4’-bipyridine. This paper reports the synthesis and characterization of a single molecule magnet, [Cu2(ɳ2-(OOCR)2(ɳ1-(OOCR)2(2,2'- bpy)2] (Complex 1), and a coordination polymer, [Cu2(ɳ2-(OOCR)2(ɳ1-(OOCR)2(2,2'-bpy)(4,4'- bpy)EtOH] (Complex 2), where R = CH3(CH2)14. These complexes are characterized by elemental analyses, FTIR and UV-vis spectroscopies, magnetic susceptibility, Thermogravimetry and optical polarized microscopy (OPM). Both complexes showed weak ferromagnetic interactions between the square pyramidal Cu(II) centres, and exhibit mesomorphisms.
