Crystal structure and molecular packing in a new organic semiconductor penta[bis(ethylenedithio)tetrathiafulvalene]-hexathiocyanato-mononitrato yttrium(III)-ethanol
A new radical cation (ET)(5)[Y(NCS)(6)NO3].C2H5OH salt was prepared by electrochemical oxidation of ET in a chlorobenzene-ethanol solution. Its crystal structure and conducting properties were examined. The salt has a layered crystal structure with a new type of molecular packing in the radical cation layer, which was called the omega-type. The observed electroconducting properties suggest that this salt is a semiconductor. (C) 2002 Elsevier Science B.V. All rights reserved.
