|Title:||Immobilization And Photoacoustic Spectroscopy Of N-(2-pyridyl)acetamide Cation Complexes Bonded To Silica Gel|
Da Paixao F.J.
|Abstract:||N-(2-Pyridyl)acetamide was covalently immobilized onto silica gel giving 1.57×10-4 mol of this molecule per gram of silica. This new bidentate chelate extracts MCl2 (M = Ni, Co, Cu) from ethanol and acetone solutions. The photoacoustic spectra of the solid complexed samples were obtained in the visible and near-infrared spectral regions and were analysed using ligand field theory. The calculated Racah parameters indicate a tetrahedral geometry for nickel and cobalt and a highly distorted octahedral geometry for the copper complex.|
