Two new coordination polymers [Pb(TIP)(1,3‐bdc)] n ( 1 ) and [Pb(Dpq)(fum)] n ( 2 ) (TIP = 2‐(2‐thienyl)imidazo[4,5‐ f ]1,10‐phenanthroline, Dpq = dipyrido[3,2‐ d :2′,3′‐ f ]quinoxaline, 1,3‐H 2 bdc = benzene‐1,3‐dicarboxylic acid, fum = fumaric acid) were synthesized by hydrothermal reactions and were characterized by elemental analyses, IR spectroscopy and single‐crystal X‐ray diffraction. Complex 1 is a one‐dimensional (1D) chain, which is bridged by 1,3‐bdc ligands. This is further extended into a three‐dimensional (3D) supramolecular structure by hydrogen bonding interactions. Compound 2 exhibits a two‐dimensional (2D) network structure, which is further stacked by π–π interactions to form a 3D supramolecular framework. The most important feature of these two complexes is that the N‐donor ligands with an extended π‐system play a crucial role in the formation and stabilization of the final supramolecular frameworks. Moreover, the fluorescence property of complex 1 was also investigated in the solid state at room temperature.
