M(hfac)2(TTF-py)2 (M = CuII, MnII; hfac = hexafluoroacetylacetonate and TTF-py=4-(2-tetrathiafulvalenyl-ethenyl)pyridine):: a new approach for π-d interactions in conducting and magnetic molecule based materials

The new coordination complexes M(hfac)(2)(TTF-py)(2) (M = Cu-II, Mn-II) in which the paramagnetic transition metal and the organic donor are covalently linked through delocalized pi system are prepared aiming with a new approach for the occurrence of pi-d interactions in conducting and magnetic molecule based materials. The structures, magnetic properties and electrochemical properties were investigated. Xray structure analysis revealed its structure is favorable for electrical conductivity.
