Structures and properties of ethylenedioxy substituted CH-TTP
Description
Most of the organic conductors based on CH-TTP derivatives, where CH-TTP is 2-(4,5-cyclohexeno-1,3-dithiol-2-ylidene)-5-(1,3-dithiol-2-ylidene)-1,3,4,6-tetrathiapentanlene, behave metallic down to low temperatures. An X-ray crystal structure analysis of CHEO-TTP(ReO 4 ) 0.38 revealed that the arrangement of the donors is close to that of the κ-BEDT-TTF salts. The band structure calculated with the tight-binding approximation suggests that the ReO 4 − salt has a closed Fermi surface similar to those of the κ-type superconductors.
