Uranyl complexes of some Schiff bases obtained by condensing salicylaldehyde with 2-aminopyridine, aniline and nitroanilines and 5-methylsalicylaldehyde with 2-aminopyridine are synthesized and characterised by elemental analysis, spectral and conductance data and magnetic susceptibility study.All the complexes are orange-red in colour, microcrystalline in nature and from compounds of the type (NO3)2 and , where LH and L are Schiff base molecules, L representing the ligand containing pyridyl nitrogen in the structure.The bonding with the metal in the complexes takes place from oxygen and hydroxyl oxygen in the two types of ligands and the imine nitrogen of the ligands.Pyridyl nitrogen does not take part in coordination.The studies show that the complexes formed are 1:2 adducts and that the complexes have coordination number eight and six, respectively.
