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（亚乙基二硫代）四硫富瓦烯（BEDT-TTF）形成许多电荷转移络合物。（BEDT-TTF）_4 [Ni（CN）_4]晶体属三斜晶系，晶胞参数为a=10.994（2），B=16.443（2），c=9.703（1），α =97.85（1），β =115.15（1），γ =95.94（1）nm。晶体中BEDT-TTF分子沿[201]方向存在沿着的面-面重叠。沿着[201]方向还观察到短S ··· S接触的分子间相互作用，室温电导率约为20 S/cm。该晶体在230 ~ 300 K之间为金属态，在160 K以下变为半导体，能隙为100 K，但电导率在160 ~ 230 K之间不随温度变化。这种电阻行为可以用晶体在160 ~ 230 K之间的相变来解释，4K时的ESR谱由g=2.013的强带和g=2.056的弱带组成。
