catena-Poly[[aqua(2,2'-bipyridine-kappa2N,N')manganese(II)]-mu-terephthalato-kappa3O,O':O"].

The title complex, [Mn(C(8)H(4)O(4))(C(10)H(8)N(2))(H(2)O)](n), takes the form of a zigzag chain, with the terephthalate dianion (tp) acting as a tridentate ligand. The Mn(II) 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) degrees. 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 pi-pi stacking interactions involving the bipy rings and the benzene ring of the tp ligand.
