Three new metal-organicframeworks, [Cu3(L1)2(OH)4]n (1), [Cu(L1)(Cl)]n (2), and [Cu(H2O)(L2)(Cl)]n (3), were synthesized under hydrothermal conditions by reaction of 4-substituted 1,2,4-triazole derivative ligands (L1 = 4-(1,2,4-triazol-4-yl)ethanesulfonate; L2 = 4-(1,2,4-triazol-4-yl)benzenesulfonate) with Cu2+ salts. The different geometry and chemical features of the ligands have yielded unique
readily yields the target molecule in short duration of time with significant yield (73%). This catalyst-free method was extended to synthesise a series of 4-substituted 1,2,4-triazoles of potential interest in coordination chemistry.
Two d10 coordination polymers based on 4-(4H-1,2,4-triazol-4-yl)benzenesulfonic acid ligand: Syntheses, structures, photoluminescence, and sensing property
solid fluorescent property of 1 and 2 have also been investigated. In complex 1, the deprotonated ligand L connected with Cd(II) metal each other to give a 3D structure, the neighboring 3D network can be connected by the C H‧‧‧π to form a final two-fold interpenetrating supramolecular 3D structure, while 2 is 3D structure formed by non-covalent interaction. The fluorescence of complex 1 shows a remarkable
