Scientific Essay from the year 2011 in the subject Chemistry — Anorganic Chemistry, 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) constants.
