制备了基于单组分金络合物和延伸的 TTF 二硫醇配体 [Au(dmdt)2]0+(1) 和 [Au(tmdt)2]0+(2) 的高导电晶体（dmdt = 二甲基四硫富瓦烯二硫醇和 tmdt = 三亚甲基四硫富瓦烯二硫醇）。根据同步辐射粉末衍射数据，成功获得了MEM电子密度2。压制粉末样品1和2在室温下的电导率分别为12和15 S cm-1。 1 的类泡利磁化率表明该系统至少在 50 K 以上基本上是金属的，而 2 在 100 K 左右表现出磁转变，而不会损失其高电导率。
Highly conducting crystals based on single-component gold complexes with extended-TTF dithiolate ligands [Au(dmdt)2]0+(1) and [Au(tmdt)2]0+(2) were prepared (dmdt = dimethyltetrathiafulvalenedithiolate and tmdt = trimethylenetetrathiafulvalenedithiolate). On the basis of the synchrotron radiation powder diffraction data, the MEM electron density of2was successfully obtained. The conductivities of compacted powder samples of1and2at room temperature were 12 and 15 S cm-1, respectively. Pauli-like susceptibility of1suggested the system to be essentially metallic at least above 50 K, while2showed a magnetic transition around 100 K without loss of its high conductivity.
