The first hybrid radical salt of bis(ethylenedithio)tetrathiafulvalene (BEDT‐TTF) using a polyoxovanadate as the counterion, (BEDT‐TTF) 5 [H 3 V 10 O 28 ]·4H 2 O, has been obtained and characterized. It contains segregated mixed‐valence 2D stacks of organic radicals interleaved by anionic layers of [H 3 V 10 O 28 ] 3– anions (see Figure). This compound exhibits high electrical conductivity at room temperature and metallic behavior down to low temperatures.
