In the chiral polymeric title compound, poly[aqua(4,4'-bipyridine)[mu(3)-S-carboxylatomethyl-N-(p-tosyl)-L-cysteinato]-manganese(II)], [Mn(C12H13NO6S2)(C10H8N2)(H2O)]n, the Mn II ion is coordinated in a distorted octahedral geometry by one water molecule, three carboxylate O atoms from three S-carboxyatomethyl-N-(p-tosyl)-L-cysteinate (Ts-cmc) ligands and two N atoms from two 4,4'-bipyridine molecules. Each Ts-cmc ligand behaves as a chiral mu(3)-linker connecting three Mn II ions. The two-dimensional frameworks thus formed are further connected by 4,4'-bipyridine ligands into a three-dimensional homochiral metal-organic framework. This is a rare case of a homochiral metal-organic framework with a flexible chiral ligand as linker, and this result demonstrates the important role of noncovalent interactions in stabilizing such assemblies.
