Preparation, X-ray crystal structure, electrical and optical properties of a new BETS charge transfer salt: k-(BETS)4Cu2C16

摘要

Molecular materials with new combinations ofproperties such as conductivity and magnetism are attracting greatinterest. Electrocrystallization of materials obtained by associationof the organic donor BETS (bis-(ethylenedithio)tetraselenafulvalene) with copper (II) chlorides leads to severaldifferent phases showing coexistence of #pi# conducting electronsand paramagnetic 3d electrons localized on copper atoms. X-raycrystal structure and conductivity measurements of the compoundk-(BETS)_4Cu_2Cl_6 are presented.
