Abstract :

The new coordination polymer[Mn(C12H8N2O4)]n takes the form of one dimensional zigzag chain built of Mn(II) cations linked by oxalate dianions. The oxalate anion coordinated as a idging tetradentate ligand with bidentate of coordination of individual oxygen atoms. The Mn(II) cation has a highly distorted octahedral geometry formed by four oxygen atoms from two bidentate oxalate anions and two nitrogen atoms from one chelating 2,2-bipyridine (bipy) ligand. The zigzag chain which run along the a-axes, further construct a three-dimensional metal-organic framework via π-stacking and C-H•••.O hydrogen bonds.
