Phosphorus Heterocycles Exceptional bonding and molecular properties are observed in mixed‐valent tetraphosphetes now accessible by a simplified synthetic protocol. Besides anisotropic absorption of visible light and remarkable 31 P NMR chemical shifts, the dispirocyclic compounds combine bis(ylidic) properties with elements of non‐classical π‐bonding.
