H-bond scheme in superstructure of Phenazine-chloranilic acid at low temperature

What is it about?

Ferroelectricity is caused by proton transfer, resulting in a superstructure.

Why is it important?

The distortions of the structure at low temperatures follows a single normal mode which can explain the direction of the polarisation close to the monoclinic axis, even though the symmetry is reduced to triclinic.
