A new (4, 6)-connected Cu(I) coordination polymer based on rare tetranuclear [Cu 4I 2] clusters: Synthesis, crystal structure, luminescent and photocatalytic properties

摘要

AbstractA new Cu(I) coordination polymer, namely [Cu5I3(L)2]n(1HL?=?3-(4-pyridyl)-5-(3-pyridyl)-1,2,4-triazolyl), was solvothermally synthesized using CuI, HL and NaI as the starting materials. Single crystal X-ray structural analysis shows that compound1features a (4, 6)-connected 3D framework employing rare tetranuclear [Cu4I2] clusters as building subunits. It exhibits intense metal-to-ligand luminescence and excellent photocatalytic activity on degradation of methylene blue (MB).Graphical abstractPresented here is a new Cu(I) coordination polymer, namely [Cu5I3(L)2]n(1HL?=?3-(4-pyridyl)-5-(3-pyridyl)-1,2,4-triazolyl), which features a (4, 6)-connected 3D topological framework using rare tetranuclear [Cu4I2] clusters as building subunits.Display Omitted
