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.
