{l_brace}[Pb{sub 3}(CPIDA){sub 2}(H{sub 2}O){sub 3}].H{sub 2}O{r_brace}{sub n}1, {l_brace}[Cd{sub 3}(CPIDA){sub 2}(H{sub 2}O){sub 4}].5H{sub 2}O{r_brace}{sub n}2, [Cd(HCPIDA)(bpy)(H{sub 2}O)]{sub n}3 (bpy=4,4'-bipyridine) and {l_brace}[Co{sub 3}(CPIDA){sub 2}(bpy){sub 3}(H{sub 2}O){sub 4}].2H{sub 2}O{r_brace}{sub n}4 were synthesized with N-(4-carboxyphenyl) iminodiacetic acid (H{sub 3}CPIDA). In 1, the CPIDA{sup 3-} ligands adopt chelating and bridging modes with Pb(II) to possess a 3D porous framework. In 2D-layer 2, the CPIDA{sup 3-} ligands display a simple bridging mode with Cd(II). The 2D layers have parallelogram-shaped channels along a axis. With bpy ligands, the HCPIDA{sup 2-} ligands in 3 show more abundant modes, but 3 still displays a 2D sheet on bc plane for the unidentate bpy molecules. However, in 3D-framework 4, the bpy ligands adopt bridging bidentate at a higher pH value and the CPIDA{sup 3-} ligands show bis-bidentate modes with Co(II). Additionally, 2D correlation analysis of FTIR was introduced to ascertain the characteristic adsorptions location of the carboxylate groups with different coordination modes in 4 with thermal and magnetic perturbation. Compounds 1, 2 and 4 exhibit the fluorescent emissions at room temperature. - Graphical abstract: A series of coordination polymers were synthesized with H{sub 3}CPIDA and transition metal ions at lower pH values. The figure displays a 3D porous framework with three parallel channels in compound 1.
