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 nonlinear dicarboxylate ligand, 4,4ʹ-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 supramulecular networks by CH…O. 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.
