Abstract
The sylithesis of several new dioxouranium(VI) complexes of Schiff bases prepared from selicylaldehyde, 5-chlorosalicylaldehyde, 5-bromosalicylaldehyde, 5-nitrosalicylaldehyde, 3,5-dichlorosalicylaldehyde, 4-methoxy-salicylaldehyde, 5-methoxysalicylaldehyae, 3-ethoxy-salicylaldehyae, 2-hydroxy-1-naphthaldehyde and ethanolamine is described. The Schiff bases behave as ONO donor tridentate, dibasic ligands. The complexes are of the type UO2L.CH3OH, where LH2 = tridentate, dibasic Schiff base. The complexes are characterised by elemental analysis, infrared and electronic spectra, conductance, magnetic susceptibility and molecular weight measurements. The complexes are monomeric, diamagnetic and octahedral. The ν (C=N), ν (C-O)phenolic, and ν(C-0) alcoholic stretch frequencies have been determined to probe the coordination sites of the ligands.
