catena-Poly[[[di-mu-acetato-kappa O-4 : O '-bis[(acetato-kappa O-2,O ')manganese(II)]]-di-mu-4,4 '-bipyridine-kappa N-4 : N '] monohydrate

The title compound, {[Mn-2(CH3CO2)(4)(C10H8N2)(2)](H2O)-H-.}(n), is a one-dimensional coordination polymer with a ladder-like structure. Two Mn-II atoms, each coordinated by a chelating acetate ligand, are bridged by two bidentate acetate ligands to form a centrosymmetric [Mn-2(CH3CO2)(4)] unit. Two 4,4'-bipyridine ligands link the [Mn-2(CH3CO2)(4)] units through Mn-N bonds to generate a molecular ladder. The water O atom lies on a crystallographic twofold rotation axis.
