title: Ultrasonic assisted synthesis of two new coordination polymers and their applications as precursors for preparation of nano-materials.
abstract: Two new isostructural coordination polymers, [Zn3(Oba)4][Me2NH2)2]·6DMF·3H2O (1) and [Cd3(Oba)4][Me2NH2)2]·2DMF·2H2O (2), were synthesized using the nonlinear dicarboxylate ligand, 4,4'-oxybis(benzoic acid) (H2oba) and characterized by IR spectroscopy and single-crystal X-ray crystallography. Single-crystal X-ray data show that 1 and 2 are two-dimensional coordination polymers that can be extended to three-dimensional supramolecular networks by CH…O interactions. These two new coordination polymers were also sonochemically synthesized while sonication time and power of irradiation influencing size and morphology of nano-structured compounds were also studied. Moreover, calcination of these coordination polymers creates ZnO and CdO nanostructures.
