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

The title complex, {[Mn(C10H8N2)(2)(H2O)(2)](C14H9O4S2)(2)}(n), contains an octahedrally coordinated Mn-II cation and 2-(2-carboxyphenyldisulfanyl)benzoate anions. The Mn-II 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 center dot center dot center dot O hydrogen bonds and C-H center dot center dot center dot pi stacking interactions. Additional intermolecular O-H center dot center dot center dot O hydrogen bonds link the cationic and anionic frameworks to form the three-dimensional crystal structure.
