Abstract

original image

Ferroelectric properties verified: Recent results presented for the complex of imidazole and L-tartaric acid are based on improper analysis and interpretation of the experimental dielectric and crystallographic data. In particular, it has now been shown that a ferroelectric-to-paraelectric phase transition in this compound occurs at 351 K, namely at a temperature 100 K higher than reported previously.
