title: Poly[[diaqua-bis(μ(2)-4,4'-bipyridine)-manganese(II)] bis-[2-(2-carboxy-phenyl-di-sulfanyl)benzoate]].
abstract: The title complex, {[Mn(C(10)H(8)N(2))(2)(H(2)O)(2)](C(14)H(9)O(4)S(2))(2)}(n), contains an octa-hedrally coordinated Mn(II) cation and 2-(2-carboxy-phenyl-disulfan-yl)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 mol-ecules. 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-carboxy-phenyl-disulfan-yl)benzoate anions that form a separate anionic two-dimensional framework via inter-molecular O-H⋯O hydrogen bonds and C-H⋯π stacking inter-actions. Additional inter-molecular O-H⋯O hydrogen bonds link the cationic and anionic frameworks to form the three-dimensional crystal structure.
