Graphic abstract: Influence of the anion ratio in the composition of mixed benzoate/pentafluorobenzoate complexes of europium on the structure and photoluminescent properties

Abstract: Mixed carboxylate benzoate (bz)/pentafluorobenzoate (pfb) complexes with different ratios of pfb and bz anions in the {Eu(EtOH)₂(pfb)(bz)₂}_n and {Eu(EtOH)(pfb)₂(bz)}_n compositions were obtained and structurally characterized. Changes in the pfb/bz ratio lead to changes in the geometry of the polymer chains and the lanthanide polyhedron, as well as to a rearrangement of the system of non-covalent interactions, which also affects the photoluminescent properties. The synthesized compounds were characterized by X-ray diffraction study, IR spectroscopy and CHN analysis; non-covalent interactions were analyzed using Hirshfeld surface analysis.

Keywords: europium(III), mixed carboxylate complexes, pentafluorobenzoate, benzoate, non-covalent interactions, photoluminescence, Hirshfeld surface analysis.
