COORDINATION COMPOUNDS OF DIMETHYL 1,1'-DIACETYLFERROCENEBIS(HYDRAZONATOCARBODITHIOATE) WITH TRANSITION METALS

摘要

A new ligand, dimethyl 1, 1'-diacetylferrocenebis (hydrazonatocarbodithioate) (H(2)L), was prepared by the condensation of 1,1-diacetylferrocene with S-methyldithiocarbazate. Its transition metal complexes, ML (1-3)H2O [M = Cu(II), Co(II), Ni(II), Zn(II)1 Cd(II) and UO2(VI)], were obtained by the reaction of hydrated metal acetate with H(2)L. The data of elemental analyses, IR, H-1 NMR, electronic spectra, molar conductivities, magnetic moments and thermal analyses show that the ligand coordinates to the metal ion in the thioenol form. These complexes are non-electrolytes in DMF and are more thermally stable than their ligand due to the formation of chelate rings. [References: 17]
