Abstract

original image

The oxidative addition of P4 to zirconium and halfnium complex fragments leads to the new polyphosphide ion Pmath image, which can be stabilized in the form of the complex 1 (Cp′ = η5-1,3-C5H3(tBu)2; M = Zr, (Hf). Addition to a rhodium complex fragment leads, inter alia, to formation of the sandwich complex 2 in which a metallatetraphosphacyclopentadiene functions as η4-P4-ligand (Cp′ = η5-C5Me4Et). 2 forms red crystals that are readily soluble in organic solvents; an X-ray structure analysis has been carried out on 2.
