Abstract

This work consists on the synthesis and structural characterization of Co(II) dinuclear complexes with N,N',N'',N'''-tetrakis(salicylidene)-1,1',2,2'phenylenetetramine (bis-salophen), and N,N',N'',N'''-tetrakis(salicylidene)-3,3',4,4'-(1,1'biphenylene)tetramine (bis-salophen), abbreviated as bis-salophen(COOH)4 and bis-salophen(COOH)4. The proposal is based on crystallization studies of the mentioned systems for structural determination and magnetic properties studies. Thus, we aim at the development of a family of dinuclear compounds, with potential applications as building blocks on the rational design of molecular magnetic systems. The distinct coordination sites due to different chemical environments of such systems give them great versatility, which plays an important role in the development of these building blocks, leading to the formation of systems with metal ions from the first transition series to lanthanides. In this scenario, these dinuclear compounds may allow the preparation of systems with distinct properties, including magnetical, optical and electrochemical properties, etc. Therefore, it is possible to start the establishment of a new compound class which can provide an important contribution to the development of new multifunctional materials.
