Figure 1: Comparison of crystal structures of 1 in the HTP and LTP.
From: Quinuclidinium salt ferroelectric thin-film with duodecuple-rotational polarization-directions

(a) Perspective view of the crystal structure in the LTP. (b) Perspective view of the crystal structure in the HTP. The same orientation of the structures was chosen for comparison purposes. H atoms were omitted for clarity.
