Polymeric chain structures based on the P8 cage (panels a,b), and helices formed from the cis chain (panels c,d). In all cases, fully atomistic structures are shown as balls‐and‐sticks representations, and the centers of the cage‐like secondary building units (SBUs) as reduced to single points are indicated by larger spheres. Dispersion‐corrected DFT computed energies are given relative to black phosphorus.
