Abstract
Expression of concern for ‘Synthesis and characterization of a novel copper carboxylate complex and a copper complex-coated polyether sulfone membrane for efficient degradation of methylene blue dye under UV irradiation: the single crystal X-ray structure of the copper carboxylate complex’ by Rupy Dhir et al., Dalton Trans., 2024, 53, 9441–9451, https://doi.org/10.1039/D4DT00871E.
Dalton Transactions is publishing this expression of concern in order to alert readers that concerns have been raised over the validity of the crystal structure presented in this article. While there is currently no doubt regarding the validity of the photocatalytic studies presented herein, the crystallographic data is not considered reliable.
An expression of concern will continue to be associated with the article while the authors work to address this matter.
