In the title compound, [Mn(C6H6O4)(C12H12N2)(H2O)]n, the cyclobutane-1,1-dicarboxylate (cbdc) ligands bridge three MnII 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 MnII 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 MnII atom, whereas the second carboxylate group coordinates two different MnII atoms.
