Descripción: The reaction of barium carbonate or hydroxide with oxydiacetic acid leads to the self-assembly of two barium oxydiacetate polymers in good yield: [Ba(oda) (.) H2O](n) (1) and [Ba(Hoda)(2)](n) (2). The products have been characterized by elemental analysis, IR, TGA and single crystal X-rav diffraction studies. The central barium atom in each mononuclear fragment is nine-coordinate in I and 10-coordinate in 2. These fragments are bridged by carboxylato groups in anti-anti conformation and through H-bonding interactions forming complex 3D networks.
