| Abstract: | Palladium(II) oxalato complexes with heterocyclic ligands have been prepared and characterized by spectroscopic and biological studies. The compounds are of the general formula Pd(ox)(L)n where ox = oxalato For n = 1, the ligand is isoxazole, 3,5-dimethylisoxazole, 2-methyl-benzoxazole, 2,5-dimethylbenzoxazole, and ethylenediamine, for n = 2, the ligand is N methylimidazole, N-ethylimidazole, N-propylimidazole, 3-amino, 5-methylisoxazole, and 5-amino 3,4 dimethylisoxazole. The Pd(ox)(L)2 soluble in water are monomeric square-planar; the Pd(ox)(L) that are little soluble in water are dimeric square-planar with the ligand bridging bidentate except to the chelate ethylenediamine. All the compounds exhibit a certain inhibitorial effect with the exception of the Pd(ox)(en) derivative. |
