For the first time, the tetrahedral diphosphorus complex [CpW(CO)(µ,η:η-P)] (Cp = CH) () is used as a connecter in supramolecular chemistry. The treatment of with Cu halides leads to the formation of the new one-dimensional (1D) linear polymers [Cu(µ-X){CpW(CO)(µ,η:η:η:η-P)}] {X = Cl (), Br (), I ()}. The coordination polymers (CPs) - are almost insoluble in organic solvents, thus, their P MAS-NMR spectra were recorded and found to be remarkably influenced by their solid-state structures. Additionally, we demonstrate that by reacting the Cp-substituted diphosphorus complex [Cp'W(CO)(µ,η:η-P)] {Cp' = CH{C(CH)}} () with CuBr, the unprecedented soluble 1D CP [Cu(µ-Br){Cp'W(CO)(µ,η:η:η:η-P)}] () is obtained. Furthermore, the reactions of with the Ag salts Ag[CFSO] and Ag[PF] result in the formation of the oligomeric dicationic species [Ag{CpW(CO)(µ,η:η:η-P)} {CpW(CO)(µ,η:η:η:η-P)}][X'] {X' = [CFSO] (), [PF] ()}.
首次将四面体二磷配合物[CpW(CO)(µ,η:η-P)]（Cp = CH）（）用作超分子化学中的连接体。用卤化铜处理会导致形成新的一维（1D）线性聚合物[Cu(µ-X){CpW(CO)(µ,η:η:η:η-P)}] {X = Cl（），Br（），I（）}。配位聚合物（CPs） - 几乎不溶于有机溶剂，因此，记录了它们的磷固态核磁共振谱，发现其受固态结构的显著影响。此外，我们证明，通过使Cp取代的二磷配合物[Cp'W(CO)(µ,η:η-P)] {Cp' = CH{C(CH)}}（）与CuBr反应，可得到前所未有的可溶性一维CP [Cu(µ-Br){Cp'W(CO)(µ,η:η:η:η-P)}] （）。此外，与银盐Ag[CFSO]和Ag[PF]的反应导致形成低聚双阳离子物种[Ag{CpW(CO)(µ,η:η:η-P)} {CpW(CO)(µ,η:η:η:η-P)}][X'] {X' = [CFSO]（），[PF]（）}。
