Abstract

The novel nickel complex with the extended-TTF dithiolate ligand [Ni(tmdt)₂] (tmdt=trimethylene dithiotetrathiafulvalenedithiolate) is the first three-dimensional single-component molecular metal with metallic state down to very low temperature (0.6 K). Recently, the direct evidence for presence of electron and hole Fermi surfaces in [Ni(tmdt)₂] was obtained by detecting the de Haars-van Alphen (dHvA) effect. We have synthesized analogous single-component molecular conductors with various ligands and central metal atoms and examined their structures and physical properties. The visible and ir spectra of single-component molecular conductors showed that these molecules have unprecedentedly small HOMO-LUMO gaps.
