Two novel Pb(II)-organic frameworks based on polycarboxylate ligands: Syntheses, structures, and luminescent properties

•Two novel Pb(II) complexes, {[Pb1.5(BPTC)]∙0.25H2O}n(1) and {[Pb(ADC)·(H2O)]}n(2), were successfully synthesized through varying the different polycarboxylate ligands.•Compound 1 exhibits a 3D porous coordination framework, which possesses a new 3-nodal (5,6,8)-connected topology.•Compound 2 shows a two-dimensional layer containing a 1D nanotube structure. In addition, compounds 1 and 2 exhibit high thermal stability and fluorescent properties in the solid state at room temperature.

Two novel Pb(II) complexes, {[Pb1.5(BPTC)]∙0.25H2O}n(1) and {[Pb(ADC)·(H2O)]}n(2), (H3BPTC = biphenyl-3,2′5′-tricarboxylate, H2ADC = 1,3-Adamantanedicarboxylic acid) were successfully synthesized through varying the different polycarboxylate ligands. The compounds were structurally characterized by elemental analysis, IR and single-crystal X-ray diffraction. Compound 1 exhibits a 3D porous coordination framework, which possesses a new 3-nodal (5,6,8)-connected topology. Compound 2 shows a two-dimensional layer containing a 1D nanotube structure. In addition, compounds 1 and 2 exhibit high thermal stability and fluorescent properties in the solid state at room temperature.
