Two new vic-dioxime ligands containing 1,3-dioxolane ring and ethylenediamine, N_-hydroxy-2-(hydroxyimino)-N-(2-{[(2-phenyl-1,3-dioxolan-4-yl)methyl]amino}ethyl)ethanimidamide (L1H2), N_-hydroxy-2-(hydroxyimino)-N-(2-{[(2-methyl-2-phenyl-1,3-dioxolan- 4-yl)methyl]amino}ethyl)ethanimidamide (L2H2) and their complexes have been prepared from chloride salts of CoII, NiII, CuII and ZnII in EtOH. The authenticity of the ligands and their complexes have been established by IR, 1H- and 13C-NMR spectra, UV-Visible spectroscopy, elemental analysis and magnetic susceptibility measurements. The complexes are mononuclear. Ligands form complexes [(L1H)2M] and [(L2H)2M] with a metal:ligand ratio of 1:2 with M = CoII, NiII and CuII. ZnII forms with ligands complexes [(Zn)(L1H)(Cl)(H2O)] and [(Zn)(L2H)(Cl)(H2O)] which have a metal:ligand ratio of 1:1. The mononuclear CoII, NiII and CuII complexes indicated that the metal ions are coordinated to ligands by two N atoms, as do most of the vic-dioximes. In the Zn(II) complexes the ligands are coordinated by theNandOatoms of the vic-dioximes.
