Figs. 1–10 show views of the structure of all five Pb5Al3F19 phases at ambient pressure. Non-octahedral ions are labelled, with Pb2+ presented in red and F in blue. The AlF6 octahedra are presented in silver. Shannon's radii are used, except for the octahedral F ions. Ferroelectric phase V structure at 160 K, along the c axis.
