چکیده انگلیسی
Here we present our last results in the search for multifunctionality in conducting molecular materials obtained by combining paramagnetic molecular complexes with organic donors to produce paramagnetic molecular metals and superconductors. The structural and physical characterization of two new molecular paramagnetic superconductors ET4[H3OM(C2O4)3].PhBr (MIII = Cr and Fe) are presented (ET = BEDT-TTF = bis(ethylenedithio)tetrathiafulvalene). These salts present a superconductor transition at Tc = 1.5 and 4.0 K, respectively and very anisotropic critical fields Hc2a â Hc2b â0.5 T and HC2C â 8 T for the Fe derivative. We will also present the structural and physical characterization of two new metallic paramagnetic systems: ET4[H3OM(C2O4)3].PhCl (M = CrIII and FeIII) and five different new semiconducting paramagnets obtained with the donor bis(ethylenediselena)tetrathiafulvalene (BEDS-TTF = BEST) and [M(C2O4)3]3â (M = CrIII and FeIII) complexes.
