报道了N-(1-(2-氨乙基)哌嗪)-苯乙二酮肟(L1H2)、N-(1-(2-氨乙基)哌嗪)-乙二酮肟(L2H2)和N，N‘-双(1-(2-氨乙基)哌嗪)-乙二酮肟(L3H2)三种新型Vic-二肟配体的合成、光谱和氧化还原性质。根据~1H核磁共振、~(13)C核磁共振和FT-IR数据，确定了它们的结构为反构型。Co(II)、Ni(II)和Cu(II)的金属与配体之比为1 ： ~2。这些配体的铜(II)络合物为方形平面，Ni(II)络合物为方形平面或八面体，而Co(II)络合物为以水分子为轴向配体的八面体。Ni(II)、Co(II)和Cu(II)金属络合物在二甲基甲酰胺中的摩尔电导(ΛM)为10−3 M，表明它们是非电解质。通过元素分析、FT-IR、UV-Vis、~1H核磁共振、~(13)C核磁共振、磁化率和摩尔电导测量，确定了配体及其配合物的结构。单核配合物的循环伏安测量提供了对还原或氧化物种在DMSO溶液中的电化学行为的了解。
The synthesis, spectroscopic, and redox properties of some metal complexes with three novel vic-dioxime ligands, N-(1-(2-aminoethyl)piperazine)-phenylglyoxime (L1H2), N-(1-(2-aminoethyl)piperazine)-glyoxime (L2H2), and N,N′-bis(1-(2-aminoethyl)piperazine)-glyoxime (L3H2)], prepared from different glyoxime and 1-(2-aminoethyl)piperazine are reported. The structure of these vic-dioximes have been determined as the anti-form according to 1H NMR, 13C NMR, and FT-IR data. The metal to ligand ratios of Co(II), Ni(II), and Cu(II) complexes were found to be 1 : 2. The Cu(II) complexes of these ligands are proposed to be square planar and Ni(II) complexes of these ligands are proposed to be square planar or octahedral, while the Co(II) complexes are proposed to be octahedral with water molecules as axial ligands. Ni(II), Co(II), and Cu(II) metal complexes are non-electrolytes as shown by their molar conductivities (ΛM) in DMF (dimethyl formamide) at 10−3 M. The structure of ligands and their complexes is proposed from elemental analysis, FT-IR, UV-VIS, 1H NMR, 13C NMR, magnetic susceptibility measurements, and molar conductivity measurements. The cyclic voltammetric measurements of the mononuclear complexes provide an understanding of the electrochemical behaviour of the reduced or oxidized species in DMSO solution.
