Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Three metal coordination polymers [Zn(bdc)(L)(H₂O)]<italic>_n</italic> (<bold>1</bold>), [Co(pta)(L)(H₂O)₂]<italic>_n</italic> (<bold>2</bold>), and [Cd(tda)(L)(H₂O)]<italic>_n</italic> (<bold>3</bold>) [H₂bdc = 1, 2‐benzene dicarboxylate acid, H₂pta = terephthalic acid, H₂tda = 2, 5‐thiophenedicarboxylic acid, L = 3, 5‐bis(imidazole‐1‐yl)pyridine] were synthesized and structurally characterized by IR spectroscopy, elemental analysis, X‐ray powder diffraction, and X‐ray single crystal diffraction. Complex <bold>1</bold> shows a three‐dimensional (3D) structure with cco topology with the symbol 6⁵<bold>·</bold>8, whereas complex <bold>2</bold> features a 3D structure with cds topology with the symbol 6⁵<bold>·</bold>8. Complex <bold>3</bold> has a 2D network constructed by the cadmium atoms bridged through the ligands tda and L. Their X‐ray powder diffraction patterns were compared with the simulated ones. Moreover, their luminescent properties were investigated in the solid state at room temperature, and the thermogravimetric analyses were carried out to study the thermal stability of the 3D networks.</p> </abstract>
