Abstract

Electrochemical oxidation of a solution containing KDy(hfac)4 (hfac, hexafluoroacetyacetone) and Bis(ethylenedithio)tetrathiafulvalene (BEDT-TTF) afforded a hybrid material formulated as [β-(BEDT-TTF)2Dy(CF3COO)4·MeCN]n. The complex crystallizes in the triclinic space group P1. The before mentioned complex has a chain structure containing 4f ions bridged by mono-anion CF3COO ligand, and acts as single-molecule magnet (SMM) at low temperature. The conducting layer was composed of partially oxidized BEDT-TTF molecules in β type arrangement. The presence of radical cation and its charge ordering was assigned on the basis of optical spectra. Electrical resistivity measurements revealed semiconducting behaviour (conductivity at room temperature of 1.1 × 10−3 S·cm−1, activation energy of 158.5 meV) at ambient pressure.
