Two template‐induced supramolecular isomers [Pb(2,3‐pyde)] n ( 1 and 2 ; 2,3‐pyde = pyridine‐2,3‐dicarboxylate) have been synthesized under hydrothermal conditions. Complex 1 displays a 2D network with a point symbol of (4 2 · 6 4 ) 2 , whereas complex 2 exhibits a 3D framework with a point symbol of (4 6 · 6 4 ) 2 . The study of the stability of the isomers demonstrates that they have high thermal stability and excellent chemical resistance to boiling water and common organic solvents. Interestingly, the two polymers evidently possess different fluorescent properties although they have the same chemical component.
