  Synthesis, Crystal Structures, and Solid-State Luminescent Properties of Diverse Ln–Pyridine-3,5-Dicarboxylate Coordination Polymers Modulated by the Ancillary Ligand

  摘要：

  Nine members of the novel Ln-pyridine-3,5-dicarboxylate coordination polymer family, namely, [Ln(PDC)(GA)](n) (Ln = Gd (1), Tb (2), Dy (3), Er (4)), [Ln(PDC)(OAc)(H2O)](n)center dot nH(2)O (Ln = Sm (5), Eu (6), Gd (7)), [Gd(PDC)(OAc)(H2O)(2)](n).nH(2)O (8), and [Tb(PDC)(1.5)(H2O)](n) (9) (PDC = pyridine-3,5-dicarboxylate, GA = glycolate, OAc = acetate), have been successfully obtained by carefully regulating the ancillary ligand or reaction temperatures. Complexes 1-4 are isomorphous two-dimensional networks generated by Ln glycolate chains and bridging PDC ligands. When the HOAc was utilized instead of glycolic acid, isomorphic three-dimensional compounds 5-7 were isolated. The Ln(3+) atoms are first bridged by acetate anions to give dinuclear clusters, which are extended by nearby six PDC ligands forming a 3D (3,6)-connected flu-topological framework. Notably, the increase of reaction temperature from 160 to 180 degrees C during the synthesis of compound 7 led to compound 8, the other 3D (3,6)-connected structure on the base of dinuclear subunits with rtl topology. Furthermore, the absence of HOAc introduced the formation of compound 9, in which each binuclear cluster links adjacent eight PDC anions to give a 3D (3,8)-connected tfz-d topological structure. The elemental analyses, XRPD, FT-IR, and TGA were also investigated to characterize compounds 1-9. Furthermore, solid-state photoluminescence measurements show that these Ln pyridine-3,5-dicarboxylate coordination polymers produce strong emissions at room temperature.
