“…In the literature, a variety of amide-based coordination polymers have been employed as catalysts for Henry and Knoevenagel condensation reactions. ,,− In this study, the synthesized compounds, particularly coordination polymers 7 – 10 , possess both Lewis acid (Co 2+ /Mn 2+ /Zn 2+ with unsaturated coordination) and basic center (amine group) functionalities. Consequently, they exhibit potential as bifunctional catalysts.…”

Ten novel transition-metal-based coordination polymers were hydrothermally synthesized using metal salts (M = Co(II), Mn(II), Ni(II), and Zn(II)) with the primary ligand 4-aminonaphthalene-2,6-dicarboxylic acid (H 2 anda) as well as auxiliary ligands (phen: 1,10-phenanthroline; 2,2′-bipy: 2,2′-bipyridine; 4,4′-bipy: 4,4′-bipyridine; bpa: bis(4-pyridyl)amine, dpe: 1,2di(4-pyridyl)ethylene or py: pyridine). The successful synthesis provided four two-dimensional (2D) and six three-dimensional (3D) coordination polymers, formulated as [Co(μ 5 -anda 9), Zn (10)). A thorough investigation was conducted using conventional methods to look at the topological types and catalytic activity of the synthesized coordination polymers. Notably, under ideal conditions, coordination polymer 7 produced good conversion in the Henry and Knoevenagel condensation of benzaldehydes, demonstrating stability, high efficacy, and recyclability as a heterogeneous catalyst.
