Self-ordering of organic-metal hybrid microstructures based on tetrathiafulvalene derivatives

Abstract Two divalent transition metal complexes of EDT-TTF-4-py (EDT-TTF-4-py = 4-ethylenedithiotetrathiafulvalenyl-pyridine) have been prepared and characterized in micro and bulk crystal forms. These hybrid microstructures were synthesized by coordinative self-assemble through a solution process. The isostructural Cu(hfac) 2 and Mn(hfac) 2 (hfac = hexafluoroacetylacetonate) complexes crystallize in the monoclinic space group P 2 1 / c . Two pyridyl N atoms from two different molecules of EDT-TTF-4-py are coordinated in the trans configuration to the metal ion of M(hfac) 2 to form an octahedral complexes. The results of the elemental analysis, FT-IR, SEM-EDX and PXRD, show the chemical composition of the microstructures which are same as that of bulk crystals. Moreover, these two microstructure compounds are precursor for both conducting and magnetic materials. These investigations show the intriguing potentials of the coordinative bond in the development of multifunctional hybrid microstructures.
