Structure of poly[di­aqua­[μ-1,2-bis­(pyri­din-4-yl)ethane-κ(2) N:N′]bis­(μ(3)-cyclo­butane-1,1-di­carboxyl­ato-κ(3) O,O′:O′′:O′′′)dimanganese(II)]

In the title compound, [Mn(C(6)H(6)O(4))(C(12)H(12)N(2))(H(2)O)](n), the cyclo­butane-1,1-di­carboxyl­ate (cbdc) ligands bridge three Mn(II) ions, forming layers parallel to the ac plane. These layers are additionally connected by 1,2-bis­(pyridin-4-yl)ethane ligands to form a three-dimensional polymeric framework. An inversion centre is located at the mid-point of the central C—C bond of the 1,2-bis­(pyridin-4-yl)ethane ligand. The coordination geometry of the Mn(II) ion is distorted octa­hedral and is built up by four carboxyl­ate O atoms, one water O atom and a pyridyl N atom. The pyridine ligand and the coordinating water mol­ecule are in a trans configuration. One carboxyl­ate group of the cbdc ligand acts as a chelating ligand towards one Mn(II) atom, whereas the second carboxyl­ate group coordinates two different Mn(II) atoms.
