• The molecular and crystal structures of EVT<SUB>2</SUB>PF<SUB>6</SUB> and EVT<SUB>2</SUB>AsF<SUB>6</SUB> [EVT=4,5-ethylenedithio-4′,5′-(vinylenedithio)tetrathiafulvalene] were determined by an X-ray diffraction method. Tight-binding band-structure calculations were made, and the results were compared with those of closely resembling conducting salts, α-(BEDT-TTF)<SUB>2</SUB>PF<SUB>6</SUB> and VT<SUB>2</SUB>PF<SUB>6</SUB> [BEDT-TTF=bis(ethylenedithio)tetrathiafulvalene; VT=bis(vinylenedithio)tetrathiafulvalene]. It was concluded that the extent of the two-dimensional nature of the band electronic structure increased systematically in the order VT<SUB>2</SUB>PF<SUB>6</SUB>, EVT<SUB>2</SUB>PF<SUB>6</SUB>, and α-(BEDT-TTF)<SUB>2</SUB>PF<SUB>6</SUB>; this result was analysed in terms of their crystal structures.
