Scholarly Essay from the year 2011 in the subject Chemistry - Anorganic Chemistry, printed single-sided, grade: 3, University of Mosul (DBS), language: English, abstract: Some new metal(II) dichloride complexes with the ligands substituted nitrones of the general formula ML2Cl2], where M= Co(II), Ni(II), Cu(II), Zn(II) and Cd(II), L=OCH=CHCH=C-CH=N(O)C6H4X (X=H, p-CH3, CH3O, CH3CO, F, Cl, and Br) have been prepared and characterized by elemental analysis, IR,1H,13C NMR and Vis/Uv spectroscopy. The IR spectral data showed that the nitrone ligands coordinated with the metal ion through the most active atom of the N-oxide to give square planner coordinate (Cu, Ni, ) complexes and (Zn, Cd, Co) tetrahedral complexes. No correlation was observed between the N-O vibrations stretching hing frequency ν(N-O) of the complexes and the Hammet (σ)
