Abstrakt:	The title salt, where BSM-TTP is 2-[4,5-bis(methylseleno)-1,3-dithiol-2-ylidene]-5-(1,3-dithiol-2-ylidene)-1,3,4,6-tetrathiapentalene, was prepared. The X-ray structure analysis reveals that the donors form teramerized columns, each of which is connected through an edge-to-edge chalcogen interaction. A tight-binding band calculation suggests that this salt is a semi-metal with small Fermi surfaces. Indeed, this salt exhibited high conductivity of σrt = 25 S cm-1 at room temperature, and showed metallic conducting behaviour down to TMI = 170 K. (© 2012 WILEY-VCH Verlag GmbH & Co.
