A new compound in the BEDT-TTF family [BEDT-TTF = bis(ethylenedithio)tetrathiafulvalene] with a tetrathiocyanatocuprate(II) anion, (BEDT-TTF)4[Cu(NCS)4]

A new compound in the BEDT-TTF family [BEDT-TTF = bis(ethylenedithio)tetrathiafulvalene] with a tetrathiocyanatocuprate(II) anion, (BEDT-TTF)4[Cu(NCS)4]

A new phase combining BEDT-TTF and [Cu(NCS)4]2– as the counter-anion, namely bis[bis(ethylenedithio)tetrathiafulvalenium] tetrathiocyanatocuprate(II) bis[bis(ethylenedithio)tetrathiafulvalene], (C10H8S8)2[Cu(NCS)4]·2C10H8S8 or (BEDT-TTF)4[Cu(NCS)4] was obtained during a galvanostatic electrocrystal...
