11 de jun. de 2024 · 中文翻译： BaCu，一种带有 Cu 阴离子的二维电子化合物. 富电子特性和低功函数赋予电子化合物在（光）电子和催化应用中优异的性能；这两个特征与电子化合物的结构拓扑、成分和价电子浓度密切相关。 然而，合成的电子化合物，特别是二维（2D）电子化合物，仅限于特定的结构原型和阴离子p区元素。 在这里，我们合成并鉴定了一种独特的 BaCu 二维电子化合物，其离域阴离子电子被限制在 BaCu 框架的层间空间。 Cu 和 Ba 原子之间的键合表现出离子特性，相邻的 Cu 阴离子形成具有金属 Cu-Cu 键合的平面蜂窝结构。 通过理论计算和实验X射线吸收近边缘结构揭示了带负电的Cu离子。
