Radicalcationsalts with halide mercurate anions were obtained by the electrochemical oxidation of bis(ethylenedioxo)tetrathiafulvalene (BEDO-TTF), and their conductivity was studied. The compounds (BEDO-TTF)4Hg3X8 (X = Cl or Br), (BEDO-TTF)4Hg3.5I9, and (BEDO-TTF)2HgBr3 possess the conductivity of the metallic type down to helium temperatures.

Spectral investigations of the new organic metal β-(EDT-DTDSF)4Hg3I8 were performed. Polarized reflectance (from 500 to 17000 cm−1) and Raman spectra of single crystals were studied at room temperature. An electronic dispersion in IR spectra was analyzed versus temperature (from 4 to 300 K) in terms of the Drude model and optical transport parameters were determined. Additionally, the optical absorption
对新的有机金属β-(EDT-DTDSF)4 Hg 3 I 8进行了光谱研究。在室温下研究了单晶的偏振反射率(500至17000 cm -1)和拉曼光谱。根据德鲁德模型分析了红外光谱中电子的色散随温度(从4到300 K)的变化,并确定了光传输参数。另外,分散在KBr颗粒中的盐粉的光吸收光谱在400–45 000 cm -1范围内测量。β-(EDT-DTDSF)4 Hg 3 I 8的振动特征的拟议分配盐基于从头算的EDT-DTDSF 0和EDT-DTDSF +正常模式。
