The first structural and compositional details of a low-stage graphite interaction compound (GIC) containing Mg are reported, with the GIC obtained by combining magnesium metal and graphite powder in ethylenediamine (en) at 100 °C under an inert atmosphere. Thermal analyses indicate the bottle-green stage 1 product has a composition of [Mg(en)]C. X-ray diffraction shows a c-axis expansion of 0.55 nm, indicating the presence of intercalate monolayers with the en cointercalate oriented perpendicular to the encasing graphene layers. Redox titration indicates two electrons are transferred per Mg. A structural model is proposed with dimeric [Mg(en)] intercalate species.
首次报道了一种含有镁的低阶石墨交互化合物（GIC）的结构和组成细节，该 GIC 通过在惰性气氛下将金属镁和石墨粉末在乙二胺（en）中于 100°C 下组合获得。热分析表明，瓶绿色阶段 1 产物的组成为 [Mg(en)]C。X 射线衍射显示 c 轴膨胀 0.55nm，表明存在夹层单层，其中 en 共夹层垂直于封装的石墨烯层。氧化还原滴定表明每个 Mg 转移两个电子。提出了一个具有二聚 [Mg(en)]夹层物种的结构模型。
