In this article, the authors respond to the comments made to their researches on the exhibition of ferroelectric properties in hydrogen bonds. They state that the new chemical elements determined with ferroelectric properties require having systematic studies for their properties. Also investigated is several fundamental property of ferroelectricity which can be reversed through spontaneous polarization in the electric field.

A new NH.N hydrogen-bonded ferroelectric crystal of [C6H12N2H]+ReO - 4 (dabcoHReO4) exhibits exceptional dielectric properties that result from the unique structure where all the bistable NH...N hydrogen bonds are parallel and directed exactly in the same sense. Consequently, the main structural origin of the spontaneous polarization of the crystal is the identical orientation of the asymmetric NH+...N hydrogen bonds along [001]. This first observation of a ferroelectric with parallel arrangement of the NH+...N bonded aggregates, gives temperature-independent and the highest spontaneous polarization ever reported for an organic or water-soluble substance.
