The selenium analogue of the unsubstituted bis‐fused tetrathiafulvalene TTP (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 π‐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 TTP had been prepared previously.
