Charge Ordering and Carrier Generation by Air Oxidation of a Nickel Complex with Selenium-Containing Extended-Tetrathiafulvalenedithiolate Ligands
The structures and electrical properties of ((Bu4N)-Bu-n)[Ni(dmstfdt)(2)] (1), ((Bu4N)-Bu-n)(2)[Ni(dmstfdt)(2)] (2), and ((Bu4N)-Bu-n)(3)[Ni(dmstfdt)(2)](2) (3), where dmstfdt = extended-tetrathiafulvalenedithiolate ligand, were examined. The fresh crystal of 1 was found to be a Mott insulator, but the crystal gradually became highly conducting because of air oxidation. Compound 3 exhibited a semiconducting charge-ordering state.
