The X-ray analysis shows that the donor arrangement of (BEDT-TTF) 3Li0.5Hg (SCN) 4(H2O)2 is close to that of β-(BEDT-TTF)2I3 and the calculated Fermi surface is closed, while α″ -(BEDT-TTF) 2CsHg(SCN)4 affords a one-dimensional band structure not along the typical side-by-side direction, but in the donor stacking direction.

摘要 制备了一种新型的三组分体系有机导体,它不仅包含一个给体和一个阴离子,还包含一个第三组分阳离子。X 射线分析表明,(BEDT-TTF) 3Li0.5Hg (SCN) 4(H2O)2 的供体排列接近 β-(BEDT-TTF)2I3 的供体排列,并且计算出的费米面是封闭的,而 α ″ -(BEDT-TTF) 2CsHg(SCN)4 不是沿着典型的并排方向,而是在施主堆叠方向上提供一维能带结构。对于锂盐和铯盐,金属-半导体转变分别发生在 170 K 和 210 K 左右。
