Novel enantiomorphic Pb-coordination polymers dictated by the corresponding chiral ligands, [Pb((R,R)-TBA)(H2O)]·1.7H2O and [Pb((S,S)-TBA)(H2O)]·1.7H2O [TBA = 1,3,5-triazin-2(1H)-one-4,6-bis(alanyl)]

Two enantiomorphic Pb-coordination polymers dictated by the corresponding chiral ligands reveal high chemical stability and a selective uptake of Congo red dye through the hydrogen bonds.
