characterized by multinuclear NMR spectroscopy and their molecular structures confirmed by powder X‐ray diffraction studies. The crystal structures consist of discrete 1,1′‐methylenedipyridinium dications and [CuCl4]2− and [AuCl4]− anions for (I) and (II), respectively. As expected, the dications form a butterfly shape; the CuII centre of [CuCl4]2− has a distorted tetrahedral configuration and the AuIII
为了探索1,1'-亚甲基二吡啶鎓盐与适当的卤化物金属盐,有机-无机杂化盐1,1'-亚甲基二吡啶鎓四氯化铜(II)反应形成有机-无机杂化离子化合物的潜在倾向, (C 11 H 12 N 2)[CuCl 4 ],(I)和1,1'-亚甲基二吡啶双[四氯化金(III)],(C 11 H 12 N 2)[AuCl 4 ] 2,(II),通过用CuCl 2和Na [AuCl 4], 分别。两种杂化盐均被分离为纯化合物,通过多核NMR光谱进行了充分表征,其分子结构已通过粉末X射线衍射研究得以证实。晶体结构分别由离散的1,1'-亚甲基二吡啶鎓和(I)和(II)的[CuCl 4 ] 2-和[AuCl 4 ] -阴离子组成。正如预期的那样,这些药膏呈蝴蝶状。[CuCl 4 ] 2-的Cu II中心具有扭曲的四面体构型,[AuCl 4 ] -的Au III中心显示方平面协调。(I)的离子种类和(II)的离子种类具有双重轴向对称性,而两个[AuCl
