A three-dimensional homochiral metal-organic framework constructed from manganese(II) with S-carboxymethyl-N-(p-tosyl)-L-cysteine and 4,4'-bipyridine.
In the chiral polymeric title compound, poly[aqua(4,4'-bipyridine)[mu(3)-S-carboxylatomethyl-N-(p-tosyl)-L-cysteinato]manganese(II)], [Mn(C(12)H(13)NO(6)S(2))(C(10)H(8)N(2))(H(2)O)](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.
