and ESI-MS, while the complex was characterized by elemental analysis, IR, and ESI-MS. The crystalstructures of the free ligand H 2 L 1 and the complex have also been determined by single crystal X-ray diffraction. The ligandchelates with metal centre with a nitrogen atom of imino moiety and an oxygen atom of enolic group. The complex shows distorted trigonal bipyramidal geometry around the metal centre
摘要 已经报道和讨论了由(Z)-2-羟基-N'-(1-氧代苊-2(1H)亚基)苯甲酰肼配体(H 2 L 1 )负载的锌(II)的络合物。乙酸锌与H 2 L 1 配体的反应导致形成单核锌(ii) 络合物[Zn(HL 1 ) 2 H 2 O]。配体 H 2 L 1 已通过元素分析、 1 H、 13 C 和 1 H COZY-NMR、IR 和 ESI-MS 表征,而配合物通过元素分析、IR 和 ESI-MS 表征。游离配体H 2 L 1 和配合物的晶体结构也已通过单晶X射线衍射确定。配体与具有亚氨基部分的氮原子和烯醇基团的氧原子的金属中心螯合。该复合物在金属中心周围显示出扭曲的三角双锥几何形状,氧原子位于赤道平面,亚氨基氮原子沿轴向。对配体及其锌配合物进行 DFT/TD-DFT 计算,以深入了解结构、电子和光学特性。研究了配合物的光致发光、荧光性质。
