Conducting dimerized cobalt complexes with tetrathiafulvalene dithiolate ligands

The syntheses, crystal structures and physical properties of novel cobalt complexes with tetrathiavulvalene-type (TTF-type) dithiolate ligands are described. Complex [[Co[(TTF-dithiolate).sub.2]].sub.2] is a novel single-component molecular conductor with a dimeric molecular structure and metallic properties down to very low temperatures.
