摘　　要：以DMF和吡啶为溶剂合成了镍的水杨醛缩水杨酰肼Schiff碱(SHSH)的配合物[Ni(py)3(SHSH)]·1.5(py)(其中py代表吡啶),成功培养出了单晶。通过UV、IR、元素分析和X射线衍射等进行了表征。中心镍离子与Schiff碱提供的2个氧原子和1个氮原子以及3个溶剂吡啶的氮原子参与了配位,形成了六配位的变形八面体构型,存在分子内氢键和分子间氢键。晶体属单斜晶系,空间群:P21/n。采用循环伏安法研究了其在吡啶和DMF溶液中的电化学性质。The crystal of nickel complex [Ni（py）3（SHSH）]＂ 1.5（py） （py=pyridine） with salicylaldehyde salicylhydrazone （SHSH） was obtained in DMF and pyridine. It has been characterized by IR, UV, element analysis and X-ray diffraction single crystal structural analysis. The crystal of the title compound belongs to monoclinic system, space group P21/n. The crystal structural analysis revealed that the center nickel（Ⅱ） is bonded to two oxygen atoms and one nitrogen atom from a tridentate ligand（SHSH） and three nitrogen atoms from three solvent pyridine molecules to form a six-coordinate distorted octahedron. There exist intra and intra molecular H-bondings among the complex. The electrochemical activity was studied in DMF and pyridine respectively with an electrochemical analyzer （CH. Instrument 650a.）.
