Abstract
- We report a synthesis of a series of molecular compounds and coordination polymers of Zn<superscript>2+</superscript>, Mn<superscript>2+</superscript> Cd<superscript>2+</superscript>, Eu<superscript>3+</superscript>, and Tb<superscript>3+</superscript> with 4-allyl-2,3,5,6-tetrafluorobenzoic acid (4-Afb) anions and 1,10-phenanthroline with compositions [Zn(H<subscript>2</subscript>O)(phen)(4-Afb)<subscript>2</subscript>] (1), [Mn(H<subscript>2</subscript>O)(phen)(4-Afb)<subscript>2</subscript>]<subscript>n</subscript>·nH<subscript>2</subscript>O (2), [Cd(H<subscript>2</subscript>O)(phen)(4-Afb)<subscript>2</subscript>]<subscript>n</subscript> (3), [Cd(phen)(4-Afb)<subscript>2</subscript>]<subscript>n</subscript> (4), [Ln<subscript>2</subscript>(phen)<subscript>2</subscript>(4-Afb)<subscript>6</subscript>] (Ln = Eu 5Eu; Tb 5Tb). It is shown that the obtained cadmium coordination polymers have various compositions and structures, depending on crystallization conditions. The prepared compounds are characterized by single-crystal XRD, powder XRD, IR spectroscopy, and CHN analysis. Noncovalent interactions are analyzed using the Hirshfeld surface analysis. It is determined that the crystal packings is mainly stabilized by π⋯π, C–H⋯F, and C–F⋯π interactions. The photoluminescent properties of the 5Eu and 5Tb complexes are studied. It is shown that the structure-forming effects of non-covalent "arene–perfluoroarene" interactions can be possibly used for preorganizing reactive functional groups in the crystal.
