Özet:

 

Two novel vic-dioxime (L1H2, L2H2) compounds bearing  hydrazone side groups and their transition metal complexes Ni(II),  Co(II), Cu(II), and Zn(II) were synthesized.  The vic-dioxime ligands  bearing hydrazone side groups were synthesized by reacting  anti-glyoximehydrazine (GH2) with 4-nitroacetophenone and  4-methylacetophenenone, respectively.  Ligands form mononuclear  complexes [(LH)2M] with a metal to ligand ratio of 1:2 with  M=Co(II)(H2O)2, Ni(II), and Cu(II).  Zn(II) forms complexes  [(LH)(H2O)(Cl)Zn] with a metal to ligand ratio of 1:1.  The Co(II)  complexes of the ligands are proposed to be octahedral with water  molecules as axial ligands, the Ni(II) and Cu(II) complexes are  proposed to be square planar, and the complexes of Zn(II) are  tetrahedral.  A chloride ion and a water molecule are also coordinated  to the Zn(II) ion.  Structural assignments are supported by a  combination of 1H-NMR, 13C-NMR, HMQC, FT-IR, elemental analyses,  and magnetic susceptibility.
