The anion radical salt α-Et2Me2N[Ni(dmit)2]2 retains metallic behavior down to 1.5 K. Planar Ni(dmit)2 units lying side-by-side along the b axis stack along the c axis in such a way that one molecule overlaps with two molecules. Such a “spanningoverlap” mode has provided two-dimensional electronic structure.
阴离子自由基盐 α-Et2Me2N[Ni(dmit)2]2 在低至 1.5 K 时仍保持金属行为。沿 b 轴并排放置的平面 Ni(dmit)2 单元沿 c 轴堆叠,使得一个分子与两个分子重叠。这种“跨越重叠”模式提供了二维电子结构。
