Abstract
The reaction of cadmium(II) chloride and 4-pyridine carboxylic acid (4-Hpyc) produces a new three-dimensional supramolecular compound [Cd(4-pyc)2(H2O)4]n (1). Compound 1 is characterized by IR spectroscopy and elemental analyses. The single crystal X-ray data show an infinite three-dimensional structure formed by the hydrogen bonding and π—π stacking interactions. The CdO nanoparticles are obtained by direct calcination at 400 °C, 500 °C and 600 °C in the air atmosphere as well as by thermolysis in oleic acid at 200 °C. The obtained cadmium(II) oxide nanoparticles are characterized by X-ray diffraction and scanning electron microscopy. This study demonstrates another potential application of cadmium(II) supramolecular compounds in the preparation of nanoscale cadmium(II) oxide materials with a specific size and morphologies.
