| Popis: | Four MII (M=ZnII , CdII , HgII ) coordination polymers were designed and synthesized based on two pyridine N-oxide bridging ligands: 3,5-bis(4-pyridyl)pyridine N-oxide and 2,6-bis(3-pyridyl)pyridine N-oxide. The resulting polymers all feature a one-dimensional chain motif and contain free pyridyl moieties. More importantly, they exhibit interesting ligand-centered (pyridyl N-oxide) catalytic behavior, and can be used as highly heterogeneous catalysts to promote the Knoevenagel condensation reaction under ambient conditions. |
