Abstract
En 中文
A series of eight coordination polymers incorporating transition metals [M = Co(II), Ni(II), Mn(II), Zn(II), and Cd (II)] were effectively produced via hydrothermal techniques. The primary ligand used in the synthesis was 2amino-[1,1 '-biphenyl]-4,4 '-dicarboxylic acid (H2abda), combined with various auxiliary ligands, including 1,10phenanthroline (phen), 2,2 '-bipyridine (bipy), 2,2 '-biimidazole (H2biim), 1,4-bis(pyrid-4-yl)benzene (bpb), and pyridine (py). This process produced one 1D, one 2D, and six 3D coordination polymers, designated as [Mn(mu 4abda)(H2O)2]n (1), [Mn(mu 4-abda)(phen)]n (2), [Mn(mu 4-adba)(bipy)]n & sdot;nH2O (3), [Cd(mu 3-abda)(bipy)]n (4), [Mn (mu -abda)(H2biim)2]n & sdot;2nH2O (5), [Ni2(mu -abda)(mu 4-abda)(mu -bpb)2(H2O)2]n & sdot;2nH2O (6), [Co2(mu -abda)(mu 4-abda) (mu -bpb)2]n & sdot;nH2O (7), and [Zn4(mu 4-abda)2(mu 3-abda) (mu 3-OH)(mu -OH)(py)2]n (8). These coordination polymers were thoroughly studied to investigate their structural topologies and catalytic efficacy. Coordination polymer 8 exhibited remarkable catalytic efficacy in the Henry reaction involving pyridine-3-aldehyde, achieving high yields under optimized conditions. It demonstrated exceptional stability, effectiveness, and reusability as a heterogeneous catalyst.
