Poly[[aqua­[μ(3)-(2,6-(2)H(2))-isonicotinato-κ(3) N:O:O′][μ(2)-(2,6-(2)H(2))-isonicotinato-κ(2) N:O]manganese(II)] ethanol solvate]

In the title compound, {[Mn(C(6)H(2)D(2)NO(2))(2)(H(2)O)]·C(2)H(6)O}(n), the Mn(II) metal centre displays a slightly distorted octa­hedral coordination geometry, provided by three O and two N atoms of five isonicotinate ligands and one O atom of a water mol­ecule. There are two types of isonicotinate anions, one acting as a bridging tridentate group and the other in a bridging bidentate fashion, to form a polymeric three-dimensional network. The structure is stabilized by intra- and inter­molecular O—H⋯O and C—H⋯O hydrogen-bond inter­actions.
