Poly[[diaquabis(μ2-4,4′-bipyridine)manganese(II)] bis[2-(2-carboxyphenyldisulfanyl)benzoate]]

Abstract

The title complex, {[Mn(C10H8N2)2(H2O)2](C14H9O4S2)2}n, contains an octahedrally coordinated MnII cation and 2-(2-carboxyphenyldisulfanyl)benzoate anions. The MnII center is situated on a crystallographic center of inversion and is coordinated by four 4,4′-bipyridine (4,4′-bipy) ligands and two water molecules. The 4,4′-bipy ligands act as bridging ligands, producing a fishing-net-like two-dimensional framework. In the crystal structure, this positively charged framework is charge balanced by 2-(2-carboxyphenyldisulfanyl)benzoate anions that form a separate anionic two-dimensional framework via intermolecular O—H...O hydrogen bonds and C—H...π stacking interactions. Additional intermolecular O—H...O hydrogen bonds link the cationic and anionic frameworks to form the three-dimensional crystal structure.
