Synthesis of vic-dioxime derivatives with hydrazone side groups and their metal complexes

WOS: 000243366000004Two novel vic-dioxime ((LH2)-H-1, L-2 H-2) 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 (GH(2)) with 4-nitroacetophenone and 4-methylacetophenenone, respectively. Ligands form mononuclear complexes [(LH)(2)M] with a metal to ligand ratio of 1:2 with M=Co(II)(H2O)(2), Ni(II), and Cu(H). 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 H-1-NMR, C-13-NMR, HMQC, FT-IR, elemental analyses, and magnetic susceptibility

Synthesis of novel tetraoxime derivative with hydrazone side groups and its metal complexes

WOS: 000292738500009In this study, the synthesis of a novel tetraoxime (LH4) derivative containing hydrazone side groups, and its transition metal complexes with Ni(II), Cu(II), Co(II), and Zn(II) ions, were reported. The ligand was synthesized by reacting anti-glyoximehydrazine (GH(2)) with terephthaldialdehyde. Polymeric complexes with Ni(II) and Co(II) and binuclear complexes with Cu(II) and Zn(II) of this tetraoxime were isolated. Structural assignments were supported by a combination of H-1-NMR, C-13-NMR, HMQC, FT-IR, UV-Vis, thermogravimetric analysis (TGA), molar conductances, elemental analyses, and magnetic susceptibility.Adnan Menderes University, TurkeyAdnan Menderes University [FEF 03009]We thank the Research Fund of Adnan Menderes University (P.No: FEF 03009), Turkey
