本文报道了第一个含硒氰根配体的金属配合物阴离子ET盐α-（ET）_2TlHg（SeCN）_4的合成及其结构。研究了不同晶向的电导率和热电势随温度的变化关系以及Shubnikov-de Haase振荡。在三个晶体学独立的ET键长分布的区别已被发现，这可能会导致在自由基阳离子层中的一些电荷本地化。详细比较了所得化合物与其硫氰酸盐类似物的结构和性质。结果表明，在α-（ET）_2TlHg（SeCN）_4盐中，不存在M=K，Tl，Rb的α-（ET）_2MHg（SCN）_4化合物的低温相变特征
Synthesis of the first ET salt with a metal complex anion containing a selenocyanate ligand, α-(ET) 2 TlHg (SeCN) 4 , and its structure are reported. The temperature dependence of conductivity and thermopower in various crystallographic directions and the Shubnikov-de Haase oscillations have been studied. Distinctions of the bond length distributions in three crystallographically independent ET have been found, which may result in some charge localization in the radical-cation layer. A detailed comparison of the structure and properties of the compound obtained to its thiocyanate analog has been performed. It has been shown that in the α-(ET) 2 TlHg(SeCN) 4 salt there is no low-temperature phase transition characteristic of the α-(ET) 2 MHg(SCN) 4 compounds with M=K, Tl and Rb
