Two novel lead-based coordination polymers, namely [Pb(cbdcp)]·0.5H 2 O·0.5CH 3 OH ( 1 ) and [Pb(cbdcp)] ( 2 ), have been solvothermally constructed by using a zwitterionic ligand 4-carboxy-1-(3,4-dicarboxy-benzyl)-pyridinium chloride (abbreviated as H 3 cbdcpCl). Compound 1 has a three-dimensional framework displaying a valence-bonded SrAl 2 topology with the 4 2 ·6 3 ·8 symbol, while compound 2 has a two-dimensional sheet structure that can be simplified into a three-dimensional π π interaction-connected topology with the {4 4 ·6 2 } 2 {4 8 ·6 15 ·8 5 } symbol. Notably, compound 1 proved to be a promising potential luminescent sensor capable of selectively detecting anions, cations and small organic molecules, especially Cr 2 O 7 2− , CrO 4 2− , Fe 3+ and nitrobenzene. A novel lead-based compound is reported as a multi-responsive luminescent sensor for detecting anions, cations and small organic molecules, especially Cr 2 O 7 2− , CrO 4 2− , Fe 3+ and nitrobenzene.
