Synthesis, structure and conduction of a novel radical cation salt, (ET)/sub 5/Dy(NCS)/sub 6/NO/sub 3/.C/sub 2/H/sub 5/OH

A new radical cation salt (ET)/sub 5/Dy(NCS)/sub 6/No/sub 3/.C/sub 2/H/sub 5/OH based on a complex dysprosium anion was prepared by electrochemical oxidation of bis (ethylenedithio)tetrathiafulvalene (ET) in a chlorobenzene-ethanol solution. Its crystal structure and conducting properties were studied. The salt has a layered crystal structure with a new type of packing of the radical cation layer, which is called /spl omega/ type. Its electrical properties show that this salt is a semiconductor.
