Fig. 3: Structural studies of (P8)n@MFM-300(In) adducts.

a The packing of the disordered nanotube of phosphorus atoms within the channels of MFM-300(In): view along c axis (left) and in (\(\bar{1}\)10) plane (right). Indium atoms are shown green, C – grey, O – red, P – pink, H – pale grey; b View of the DFT-optimised double helix; c) view of the fragment of the double helix refined from powder diffraction data; d Comparison of P8 unit with other Pn cluster fragments predicted or experimentally observed in polymeric phosphorus allotropes.
