Title: A series of 2D lanthanide (III) coordination polymers constructed from 2-(pyridin-3-yl)-1H-imidazole-4,5-dicarboxylate

Abstract

Reactions of 2-(pyridine-3-yl)-1H-4,5-imidazoledicarboxylic acid (H{sub 3}PyIDC) with a series of Ln(III) ions affords ten coordination polymers, namely, {l_brace}[Ln(H{sub 2}PyIDC)(HPyIDC)(H{sub 2}O){sub 2}]{center_dot}H{sub 2}O{r_brace}{sub n} [Ln=Nd (1), Sm (2), Eu (3) and Gd (4)], {l_brace}[Ln(HPyIDC)(H{sub 2}O){sub 3}]{center_dot}(H{sub 2}PyIDC){center_dot}H{sub 2}O{r_brace}{sub n} [Ln=Gd (5), Tb (6), Dy (7), Ho (8) and Er (9)], and {l_brace}[Y{sub 2}(HPyIDC){sub 2}(H{sub 2}O){sub 5}]{center_dot}(bpy){center_dot}(NO{sub 3}){sub 2}{center_dot}3H{sub 2}O{r_brace}{sub n} (10) (bpy=4,4 Prime -bipyridine). They exhibit three types of networks: complexes 1-4 are isomorphous coordination networks containing neutral 2D metal-organic layers, while complexes 5-9 are isomorphous, which consist of cationic metal-organic layers and anionic organic layers, and complex 10 is a 2D network built up from 4-connected HPyIDC{sup 2-} anion and 4-connected Y(III) ions. In addition, thermogravimetric analyses and solid-state luminescent properties of the selected complexes are investigated. They exhibit intense, characteristic emissions in the visible region at room temperature. - Graphical abstract: Structure variation of ten Ln(III) complexes is attributed to the lanthanide contraction effect and various coordination modes of H{sub 3}PyIDC ligands.
