One copper(II) coordination polymer (CP) [Cu(L)(L-/(center dot H2O](n)center dot(NO3 )(2H(2)O) (1) (1D zig-zag chain) (where L stands for C6H5NO2 (isonicotinic acid) and L-/ is C12H8N2 center dot H2O (1,10-phenanthroline) has been synthesized following two different experimental approaches, the hydrothermal and sonochemical irradiation methods. Independently of the methodology used, the same crystalline phase is obtained for the complex. Single crystal X-ray analyses on compound 1 illustrated that Cu2+ ions are 5-coordinatedshowing the role of sonochemistry to modulate both morphology and dimensions of the resulting crystalline material. In order to study the effects of solvent and time of reaction on the formation of [Cu(L)(L-/(center dot H2O](n)center dot(NO3 )(2H(2)O) (1) coordination polymer, some experiments were designed and four samples of 1 were synthesized by sonochemical process. Less time of reaction resulted in the formation of compound 1 microrods. With more time of reaction, various morphologies mainly microhexagonal of 1 were obtained. These four samples have been used as new precursors for the preparation of copper(II) oxide micro crystals via solid-state thermal decomposition process. Flower and rod micro crystals of copper(II) oxide could be prepared from 1. These micro crystals were characterized by IR spectroscopy, X-ray powder diffraction (XRD) and Scanning Electron Microscopy (SEM).
