From: Pressure-induced zigzag phosphorus chain and superconductivity in boron monophosphide
Predicted structures of BP at ambient and high pressures.
The green and pink balls represent B and P atoms, respectively. (a) and (b) The high-pressure phase C2/m. (c) and (d) The high-pressure phase P42/mnm. One-dimensional phosphorus chain is formed in the structure of C2/m.
