摘要

The coordination compounds, [Cu-2(Htba)(tba) Cl] (1) and [Ag-2(Htba)(tba)(NO3)] (2), were synthesized under solvothermal conditions by using a triazolate-carboxylate bifunctional organic ligand 4-(4H-1,2,4-triazol-4-yl) benzoic acid (Htba). X-ray single crystal diffraction analyses for the two complexes revealed that compounds 1 and 2 exhibit one-dimensional (1D) chain structures with uncoordinated carboxylic groups, which are further connected by O-H center dot center dot center dot O hydrogen bonds into 3D, threefold interpenetrating supramolecular frameworks with different topologies belonging to 4-connected and (2,4)-connected nets with the (4(2).8(2).10(2))(4(3).6(2).8)(2)(4(4).6(2)) and (12(5).16)(12)(2) Schlafli symbols, respectively. The photoluminescent measurements reveal that both 1 and 2 exhibit bluish-purple emissions in the solid state at room temperature. In addition, the compound 2 can serve as an antenna for sensitizing the visible-emitting of the lanthanide cations to display their characteristic emissions.
