At variance with white phosphorus , the most reactive allotrope of the element, which is unstable and ignites spontaneously in air, the new η 1 ‐ tetrahedro ‐tetraphosphorus complexes [Cp*M(PR 3 ) 2 ( η 1 ‐P 4 )]Y (M=Fe, Ru; Y=Cl, PF 6 , BPh 4 , BAr $\rm{^{\prime }_{4}}$ ; Cp*=C 5 Me 3 the structure of the [Cp*Fe(Ph 2 PCH 2 CH 2 PPh 2 )( η 1 ‐P 4 )] + ion is depicted) exhibit a surprising and unprecedented thermal stability and an astonishing reluctance to react with oxygen and other oxidants.
