摘要:
New metal chelates of copper, lead and zinc with salicylaldoxime (SALO) and its derivatives have been prepared. The chelates have been characterized by elemental analysis, atomic absorption, infrared and UV spectroscopy. SALO behaves as a bidentate ligand forming neutral metal chelates through the phenolic oxygen and the oxime nitrogen. The M-O stretching frequencies for the transition metals show good agreement with the Irving-William's stability order Cu > Zn > Pb. Similar trend is seen for the M-N stretching frequencies in IR and the shift in transitions from UV spectral data for the metal chelates. (C) 1998 Elsevier Science B.V. All rights reserved.
