The oxidative addition of P 4 to zirconium and halfnium complex fragments leads to the new polyphosphide ion P 4 2⊖ , which can be stabilized in the form of the complex 1 (Cp′ = η 5 ‐1,3‐C 5 H 3 ( t Bu) 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 η 4 ‐P 4 ‐ligand (Cp′ = η 5 ‐C 5 Me 4 Et). 2 forms red crystals that are readily soluble in organic solvents; an X‐ray structure analysis has been carried out on 2 .
