The reaction of a P-4 butterfly complex with yellow arsenic yields the largest mixed PnAsm ligand complexes synthesized to date. [{CpFe(CO)(2)}(2)(,(1:1)-P-4)] reacts with As-4 to yield [{CpFe}(2)(,(4:4)-PnAs4-n)] and [CpFe((5)-PnAs5-n)]. Mass spectrometry together with NMR spectroscopy and X-ray crystallography give clear evidence about the arrangement of the E positions within the cyclo-E-5 and E-4 moieties of the products. Moreover, the results of DFT calculations agree well with the experimental determined outcomes. By coordinating the E-4 complex [{CpFe}(2)(,(4:4)-PnAs4-n)] with CuCl, a rearrangement of the E positions occurs in favor with a preferred phosphorus coordination towards copper atoms in the resulting 1D polymeric chain.
