Abstract
] (Ln = Eu (4Eu), Tb (4Tb)). It was found that the introduction of a second type of anion into the studied compounds improves the photoluminescence properties and alters the geometry of the metal core, the polyhedra of rare-earth elements (REEs), and the system of non-covalent interactions compared to benzoate and pentafluorobenzoate complexes.
