Abstract In the present study, we describe a reaction of Cu(OAc) 2· H 2 O and Gd(NO 3 ) 3· 6H 2 O with equimolar amounts of the asymmetric salamo-type ligand 6-methoxy-6′-ethoxy-2,2′-[ethylenedioxybis(azinomethyl)]diphenol (H 2 L) generated by Schiff base condensation of 2-[ O -(1-ethyloxyamide)]oxime-3-methoxy-phenol with 3-ethoxysalicylaldehyde to obtain a novel 3 d –4 f hetero-polynuclear complex [{Cu(L)Gd(NO 3 ) 3 } 2 ] [Cu(L)Gd(NO 3 ) 3 ] 2 . The complex is fully characterized by X-ray diffraction (XRD), elemental analyses, FTIR and UV-Vis spectra. The phase purity is clearly confirmed by powder XRD. In the [Cu II –Gd III ] complex, the coordination environments of Cu II ions are different, but the apical coordination atoms to the Gd III ions are nearly identical. The antibacterial and fluorescent properties of the H 2 L ligand and the [Cu II –Gd III ] complex are also investigated. Supramolecular interactions are studied in detail.

由不对称 SALAMO 基配体构建的新型抗菌活性物质 [CuII-GdIII] 复合物：合成和结构表征

摘要 在本研究中，我们描述了 Cu(OAc) 2· H 2 O 和 Gd(NO 3 ) 3· 6H 2 O 与等摩尔量的不对称萨拉莫型配体 6-甲氧基-6'-乙氧基-通过 2-[ O -(1-乙氧基酰胺)]肟-3-甲氧基-苯酚与 3-乙氧基水杨醛的席夫碱缩合生成 2,2'-[乙二氧基双(叠氮基甲基)]二苯酚 (H 2 L)，得到一种新型的 3 d –4 f 杂多核络合物[{Cu(L)Gd(NO 3 ) 3 } 2 ] [Cu(L)Gd(NO 3 ) 3 ] 2 。该复合物通过 X 射线衍射 (XRD)、元素分析、FTIR 和 UV-Vis 光谱进行了全面表征。通过粉末 XRD 清楚地证实了相纯度。在[Cu II -Gd III ]配合物中，Cu II 离子的配位环境不同，但Gd III 离子的顶配位原子几乎相同。还研究了 H 2 L 配体和 [Cu II -Gd III ] 配合物的抗菌和荧光特性。详细研究了超分子相互作用。
