Communication: The selenium analogue of the unsubstituted bis-fused tetrathiafulvalene ITP (2,5-bis(1,3-dithiol-2-ylidene)-1,3,4,6-tetrathiapentalene) has been synthesized and the conducting properties and crystal structure of its molecular complexes are presented. TTP is a promising pi-electron framework for the preparation of organic molecular metals because of its strong tendency to yield radical cation salts that retain metallic conductivity down to liquid helium temperature regardless of the counteranion. However, only poorly characterized derivatives of the selenium-based ITP had been prepared previously.
