The crystal structure of dypingite: understanding the long-range disorder. Corrigendum

An error in the article by Sednev-Lugovets et al. [J. Appl. Cryst. (2025), 58, 1908–1919] is corrected.

The article by Sednev-Lugovets et al. (2025) contains a factual error in the description of the TGA–DSC results: in the discussion of Fig. 6, the thermal effect at approximately 62 °C is described as exothermic, whereas it is in fact endothermic. The second paragraph of Section 3.2 should read as follows:

The compositional difference between the hydrated and dehydrated samples of synthetic dypingite was studied by thermogravimetric analysis, coupled with differential scanning calorimetry (TGA–DSC). On heating, the two samples underwent similar decomposition stages (Fig. 6) with peak temperature (T_p) events at 120 and 245 °C, corresponding to the release of water from the material. The third process at T_p = 433 °C was associated with the sample decarbonation. While these findings are consistent with previous reports, the TGA–DSC curve of the hydrated sample demonstrated an additional decomposition step, with a pronounced endothermic effect at T_p = 62 °C (Raade, 1970; Suzuki & Ito, 1973; Canterford et al., 1984; Yamamoto et al., 2022; Frost et al., 2008). This was associated with desorption of water previously accommodated by the sample during the hydration process.
