Construction of metal–organic frameworks with transitional metals based on the 3,5-bis(4-pyridyl)-1H-1,2,4-triazole ligand
چکیده انگلیسی

Based on the versatile ligand 3,5-bis(4-pyridyl)-1H-1,2,4-triazole (Hbpt) derived from an in situ metal/ligand reaction, a series of coordination compounds CoCl4(H3bpt)(H2O) (1), Cu(H2bpt)2(SO4)2(H2O)6 (2), [Ag(bpt)]n (3), [Co(Hbpt)(pa)]n (4), [Co(Hbpt)(pda)]n (5) and [Cu(Hbpt)(pda)(H2O)]n (6) have been constructed (pa = phthalate, pda = 1,3-phenylenediacetate). The structures of these targeted complexes have been characterized by X-ray single-crystal diffraction techniques. Structural analysis reveals that Hbpt adopts versatile coordination modes to arrange the metal ions in 0-D point, simple (4,4) layers and dinuclear core chains in 1–3, which are further extended via the benzenedicarboxylate connectors to give rise to a variety of coordination networks such as (4,4), (412 · 63), (64 · 82) topologies in 4–6. The supramolecular organization through hydrogen bonds is analyzed for these complexes and thermal stability of these crystalline materials has been explored by TG-DTG.

The versatile ligand 3,5-bis(4-pyridyl)-1H-1,2,4-triazole was synthesized using an in situ metal/ligand reaction. Based on which, six coordination complexes have been prepared, in which the bpt ligand manages the metal ions to form 0-D point, (4,4) layers and a variety of 3-D (412 · 63), (64 · 82) topological networks.Figure optionsDownload as PowerPoint slide
