The Potential of the Diphosphorus Complex [CpW(CO)(η-P)] as an Organometallic Connecter in Supramolecular Chemistry.

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] ()}.
