Abstract
Retraction of ‘Ni2[LnCl6] (Ln = EuII, CeII, GdII): the first LnII compounds stabilized in a pure inorganic lattice’ by Bianca Baldo et al., Chem. Commun., 2018, 54, 7531–7534.
We, the named authors hereby wholly retract this Chemical Communications article due to concerns with the interpretation of the data in the published article.
In the article crystal structures were identified by the authors as Ni2[LnCl6]. Subsequent analysis of the data by independent experts suggest that the structure is a better match for the compound [Ni(NH3)6]Cl2. The authors suggest that there may be a mixture of compounds present in their material, but it has not been possible to obtain convincing data for the lanthanide crystals at this time.
Given the significance of the concerns, the validity of the data and, therefore, the conclusions presented in this paper are no longer reliable.
