Bis (ethylenedithio) tetrathiafulvalene (BEDT-TTF) forms many charge transfer complexes. The crystal of (BEDT-TTF)_4 [Ni(CN)_4] belongs to the triclinic pl with the lattice constants of a=10.994 (2), b=16.443 (2), c=9.703 (1), alpha=97.85 (1), beta=115.15 (1), gamma=95.94 (1)ﾟ. In the crystal, there exists the face to face overlap of the BEDT-TTF molecules along the [201] direction. The intermolecular interaction by the short S ・・・ S contact is also observed along the [201] direction.The room temperature conductivity was about 20S/cm. The crystal was metellic between 230 and 300K and became semi-conductive with an energy gap of 100K below 160K, although the temperature dependence of the conductivity was not obtween 160 and 230K. This kind of resistance behavior may be explained by the phase transition of the crystal between 160 and 230K.The ESR spectrum at 4K consists of the strong band at g=2.013 and the weak band at g=2.056.

双(乙撑二硫)四硫富瓦烯(BEDT-TTF)形成许多电荷转移配合物(BEDT-TTF)_4 [Ni(CN)_4]晶体属于三斜晶系pl，晶格常数为a=10.994 (2), b。 =16.443 (2), c=9.703 (1), α=97.85 (1), beta=115.15 (1), gamma=95.94 (1)ﾟ 晶体中，BEDT-TTF 分子沿[201]方向存在面对面重叠，由短S ・・・ S 引起的分子间相互作用。沿[201]方向也观察到接触。室温电导率约为20S/cm，晶体在230至300K之间呈金属性，并变为半导体性。 100K 的能隙低于 160K，尽管电导率的温度依赖性不在 160 和 230K 之间，这种电阻行为可以通过晶体在 160 和 230K 之间的相变来解释。4K 下的 ESR 谱由下式组成。强带位于 g=2.013 处，弱带位于 g=2.056 处。
