We report the synthesis, crystal and band structures, and transport properties of organic conductor κ-(ET)2Cu[Au(CN)2]Cl [ET = bis(ethylenedithio)tetrathiafulvalene], which has a triangular spin–lattice (S = 1/2) composed of (ET)2•+ dimers and polyanions with no disorder. The anisotropy of triangular lattice t′/t = 1.19 and physical properties indicate that this material is the first ET-based quantum-spin-liquid candidate having a nearly regular triangular lattice with a disorder-free anion.

具有无序聚阴离子的三角晶格有机莫特绝缘子。

我们报告了有机导体κ-(ET)2 Cu [Au(CN)2 ] Cl [ET =双(乙烯二硫代)四硫富瓦烯]的合成,晶体和能带结构以及传输性质,它具有三角形的自旋晶格(S = 1 / 2(ET)组成)2个•+二聚体和聚阴离子,无紊乱。三角形晶格的各向异性t '/ t = 1.19,物理性质表明,该材料是第一个基于ET的量子自旋液体候选物,具有近似规则的三角形晶格和无序阴离子。
