Özet

In this work, a novel heterocyclic dioxime (2,3-hydroximino-4-phenyl-6-phenlyazo-1-thia-4,5-diazacyclohexa-5-diene, H2L) was synthesized by reacting dithizone with cyanogen di-N-oxide. H2L forms mononuclear complexes [(HL)(2)M] with a metal-ligand ratio of 1:2 with M = Ni(II), Co(II) and Cu(II). Zn(II), Cd(II) and Hg(II) form with H2L complexes [(HL)Cl(H2O)M] which have a metal-ligand ratio of 1:1 and contain a six-membered chelate ring. Structures of these compounds are proposed based on elemental analyses, U.V.-Visible, IR, H-1 NMR mass spectra and magnetic susceptibility measurements.
