説明

<jats:title>Abstract</jats:title> <jats:p>Selenium analogues of TMET-TTP (2-(4,5-bisthiomethyl-1,3-dithiol-2-ylidene)-5-(4,5-ethylenedithio-1,3-dithiol-2-ylidene)-1,3,4,6-tetrathiapentalene) 1b-d have been synthesized. The iodine salt (1b)4I3 exhibits moderately high conductivity (σrt=13S cm−1) with semiconducting temperature dependence, and the donor arrangement is θ-type. The present θ-type salt as well as TMET-TTP salts is located at the insulating limit in the universal phase diagram of θ-phases.</jats:p>
