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.

One-dimensional polymers based on silver(I) cations and organometallic cyclo-P3 ligand complexes.

The synthesis and characterization of the first supramolecular aggregates incorporating the organometallic cyclo-P3 ligand complexes [CpRMo(CO)2(eta3-P3)] (CpR=Cp (C5H5; 1a), Cp* (C5(CH3)5; 1b)) as linking units is described. The reaction of the Cp derivative 1a with AgX (X=CF3SO3, Al{OC(CF3)3}4) yields the one-dimensional (1D) coordination polymers [Ag{CpMo(CO)2(mu,eta3:eta1:eta1-P3)}2]n[Al{OC(CF3)3}4]n (2) and [Ag{CpMo(CO)2(mu,eta3:eta1:eta1-P3)}3]n[X]n (X=CF3SO3 (3a), Al{OC(CF3)3}4 (3b)). The solid-state structures of these polymers were revealed by X-ray crystallography and shown to comprise polycationic chains well-separated from the weakly coordinating anions.
