Aiding and abetting a wanted radical : The neutral phosphorus radical [ . P{NV[N(Np)Ar] 3 } 2 ] (Np=neopentyl, Ar=3,5‐Me 2 C 6 H 3 ) exists as a monomer in the solid state and is resonance‐stabilized by two nitridovanadium trisanilide metalloligands through the V IV /V V redox couple (see EPR trace and calculated SOMO of [ . P{NV[N(Me)Ph] 3 } 2 ]). The compound undergoes radical reactions at its phosphorus center to form diamagnetic compounds.
