Pentaphosphaferrocenes [Cp Fe(η -P )] (Cp*=η -C Me ) (A), Cp''=η -C H tBu -1,3 (B)) are excellent building blocks for polymeric assemblies in supramolecular chemistry in combination with coinage metal salts of weakly coordinating anions such as AgSbF . Adding rigid aromatic dinitriles ortho/meta/para-(NC) C H in a one-pot reaction between [Cp Fe(η -P )] and AgSbF leads to various coordination polymers (CPs) by a three-component self-assembly. The sterical demand of the differently substituted cyclopentadiene ligands as well as the rigid constitution of the isomeric dinitriles (NC) C H play a key role in the formation of the isolated CPs. All CPs were characterized by NMR spectroscopy, mass spectrometry, elemental analysis, and single-crystal X-ray diffraction.
五磷二茂铁[CpFe(η-P)]（Cp*=η-CMe ）（A），Cp''=η-CHtBu-1,3（B）））与弱配位阴离子的货币金属盐（如 AgSbF ）结合，是超分子化学中聚合组装的极好构建块。在[CpFe(η-P)]和 AgSbF 的一锅反应中添加刚性芳香二腈邻/间/对-（NC）C H，通过三组分自组装得到各种配位聚合物（CP）。不同取代的环戊二烯配体的空间需求以及异构体二腈（NC）C H 的刚性结构在孤立 CPs 的形成中起着关键作用。所有 CPs 均通过 NMR 光谱、质谱、元素分析和单晶 X 射线衍射进行了表征。
