Both of them crystallize in the P21/n space group, yet they are not isomorphous. Despite the intrinsic difficulty to distinguish between F− and OH− by X-ray diffraction, the ability of the OH ligand in complex 2 to establish intramolecular OH…F hydrogen bonding with one of the CF3 groups in cis position enables a clear differentiation from the fluoride complex 1. Given the tendency of late-transition metal fluorides to undergo hydrolysis, much caution should be taken when ascribing the identity of a fluoride ligand by X-ray diffraction methods, especially where unusual geometries are implied. info:eu-repo/grantAgreement/ES/DGA/E17-23R info:eu-repo/grantAgreement/ES/MICIU/PID2021-122869NB-I00 info:eu-repo/grantAgreement/ES/MICIU/PID2024-155563NB-I00 info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Joven-Sancho, Daniel Universidad de Zaragoza (orcid)0000-0002-0204-7713 Baya, Miguel Universidad de Zaragoza (orcid)0000-0002-2492-625X Martín, Antonio Orduna, Jesús (orcid)0000-0003-3514-2570 Menjón, Babil (orcid)0000-0001-9045-5102 2010 760 Universidad de Zaragoza Dpto.
