A new pillared-layer 3D coordination polymer involving in situ generated formate

• The 3D polymer is constructed by pillared-layer structures.
• The polymer contains in situ generated formate from the decomposition of solvent DMF.
• The compound displays fluorescence property.

A new Cd-based coordination polymer, [Cd(cpt)(HCOO)]n (1), has been synthesized from 1-(4-carboxyphenyl)-1,2,4-triazole) ligand (Hcpt). The structure was characterized through X-ray crystallography, elemental analysis, and IR spectrum. Compound 1 presents a three-dimensional (3D) pillared-layer structure constructed by metal-formate layers and cpt− ligands. Moreover, the unusual formate anions are generated in situ from the decomposition of DMF precursors. The fluorescence property of 1 in solid state was also researched.

A new pillared-layer 3D coordination polymer, [Cd(cpt)(HCOO)]n (1), has been constructed based on 1-(4-carboxyphenyl)-1,2,4-triazole) ligand (Hcpt). It is noteworthy that the polymer contains a novel 2D metal-formate layer by in situ generating formate ligands from decomposition of DMF. Additionally, the fluorescence property of 1 was discussed.Figure optionsDownload as PowerPoint slide
