Title: Effect of ring coordination of pyridine-3,5-dicarboxylate and metatungstate to Ln ions on metatungstate structure: Synthesis, structure and optical property of four new compounds

Abstract

Four novel compounds based on {alpha}-metatungstate [H{sub 2}W{sub 12}O{sub 40}]{sup 6-} (W{sub 12}) and Ln-organic complexes, (NH{sub 4}){sub 4}[Ln{sub 2}(L){sub 2}(H{sub 2}O){sub 9}(H{sub 2}W{sub 12}O{sub 40})].nH{sub 2}O (Ln=Eu{sup III} (1), Gd{sup III} (2), Dy{sup III} (4), n=11; Tb{sup III} (3), n=12; L=pyridine-3,5-dicarboxylate dianion) have been synthesized in aqueous solution and characterized by element analysis, IR spectrometry and thermogravimetric analysis. Single-crystal X-ray diffraction analyses reveal these compounds are isostructural with a P21/n space group. The W{sub 12} cluster acting as a tridentate ligand connects three Ln{sup 3+} ions, in turn, each Ln2 ion links two W{sub 12} clusters, as a result, a W{sub 12}-Ln polymeric chain is formed. Coordination of pyridine-3,5-dicarboxylate ligands to the Ln{sup 3+} ions leads to a Ln-L polymeric chain. The two chains, W{sub 12}-Ln and Ln-L, share Ln2 ions, resulting in a 2-D layer. Ring coordination of pyridine-3,5-dicarboxylate and W{sub 12} to the Ln ions changes some bond angles of W{sub 12} that leads to a slight distortion of W{sub 12} and splitting of vibration band of W-Oc-W. Solid-state photoluminescence properties of compounds 1-4 have been investigated. - Graphical abstract: Four two-dimensional {alpha}-metatungstate and Ln-pyridine-3,5-dicarboxylate compounds have been synthesized.
