Three MnII-terephthalate coordination polymers, {MnII(tp)(bpy)(H2O)}n (1), {Mn3II (tp)6 / 2 (bpy)2 · (dmf)}n (2) and {MnII(tp)(phen)}n (3) (tp = terephthalic dianion, bpy = 2,2′-bipyridine, phen = 1,10-phenanthroline) have been synthesized and characterized by single crystal X-ray diffraction studies and low temperature (2-300 K) magnetic measurements. The structure analysis of 1-3 show that they all are coordination polymers composed of Mn atoms as nodes and terephthalate dianions as spacers. Interestingly, compound 1 consists of 1D infinite zigzag chains, while compound 2 consists of 2D sheets and compound 3 has a 3D framework structure. The study of the temperature dependent magnetic susceptibilities revealed that all of the polymers show antiferromagnetism.

The title complex, [Mn(C8H4O4)(C 10H8N2)(H2O)]n, takes the form of a zigzag chain, with the terephthalate dianion (tp) acting as a tridentate ligand. The MnII center is surrounded by two tp ligands, one water molecule and one 2,2′-bipyridine (bipy) ligand and exhibits a severely distorted octahedral coordination environment, with cis angles ranging from 57.31 (8) to 123.97 (11)°. The complete solid-state structure can be described as a three-dimensional supramolecular framework stabilized by hydrogen-bonding interactions involving the coordinated water molecule and the carboxy O atoms of the tp ligands, and by π-π stacking interactions involving the bipy rings and the benzene ring of the tp ligand.
