Five new coordination polymers (CPs), namely {Pb_1.5(L)} (1), {Pb₃(L)₂(2,2′-bpy)·2.5H₂O} (2), {[Pb(HL)(phen)]·H₂O} (3), {Ag₂(HL)} (4) and {Ag(H₂L)(phen)} (5), have been constructed by using 1-(4-carboxybenzyl)-1H-pyrazole-3,5-dicarboxylic acid (H₃L) as an organic ligand. Compound 1 reveals a three-dimensional (3D) (4,6,7)-connected framework with the point symbol of {4¹⁰·6⁵}{4⁶}₂{4⁸·6¹³}₂. Compound 2 exhibits a novel (3,6)-connected 3D framework based on a trinuclear Pb(II) cluster with point symbol {4².6}₂{4⁴.6².8⁸.10}. Compound 3 is a 1D chain that is further assembled into a 3D supramolecular framework by hydrogen-bonds. Compound 4 shows a (3,6)-connected 3D structure based on a tetranuclear Ag(I) cluster with {4·6²}₂{4²·6¹⁰·8³} topology. Compound 5 is a 0D structure, and can be further expanded into a 3D supramolecular network by various weak interactions. The solid-state luminescent spectra have been measured at room temperature. The results show that compounds 1-5 exhibit strong luminescent emission in the visible region, and can be tunable by varying excitation wavelengths.
