Abstract
Expression of concern for ‘Valence tautomeric interconversion of bis-dioxolene cobalt complex with imino-pyridine functionalized by TEMPO moiety in solid solutions with isostructural nickel analogue: phase transitions and monocrystal destruction’ by Michael P. Bubnov et al., Dalton Trans., 2024, 53, 9151–9160, https://doi.org/10.1039/D4DT00453A.
Dalton Transactions is publishing this expression of concern in order to alert readers that concerns have been raised over the validity of the conclusions of this article. These concerns relate to the elemental composition of the crystalline materials reported herein. While there is no doubt the authors have produced solid solutions, the specific Co/Ni ratios stated are not considered to be adequately supported. An expression of concern will continue to be associated with this article until the authors can provide sufficient quantitative support for their claims.
