چکیده
In the title compound, [Mn(C6H6O4)(C12H12N2)(H2O)] n , the cyclo-butane-1,1-di-carboxyl-ate (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 octa-hedral and is built up by four carboxyl-ate O atoms, one water O atom and a pyridyl N atom. The pyridine ligand and the coordinating water mol-ecule are in a trans configuration. One carboxyl-ate group of the cbdc ligand acts as a chelating ligand towards one Mn(II) atom, whereas the second carboxyl-ate group coordinates two different Mn(II) atoms.
