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.

bis（乙烯基硫硫代）四硫硫酸盐（BEDT-TTF）形成许多电荷转移复合物。 （bedt-ttf）_4 [ni（cn）_4]的晶体属于三斜pl，带有a = 10.994（2）的晶格常数，b = 16.443（2），c = 9.703（1），alpha = 97.85（1），beta = 97.85（beta = 97.85（beta = 115.15（15.15（1），1），gmam，gamn99999。9999999。999999。999999。在晶体中，存在沿[201]方向的BEDT-TTF分子的面对面重叠。沿[201]方向也观察到短距离接触的分子间相互作用。室温电导率约为20 s/cm。晶体在230至300K之间是金属的，尽管电导率的温度依赖性在160和230k之间获得，但能量间隙为100K以下100K，其能量间隙为100K。这种抗性行为可以通过160至230k之间的晶体的相变来解释。4K处的ESR光谱由g = 2.013的强条组成，而G = 2.056的弱条带组成。
