Abstract

The titled mononuclear complex [Cu (L)] with the formally tetradentate schiff base ligand, [N,N’-bis (2-hydroxy-3-methoxybenzylidene)-1,3-diaminopropan-2-ol] has been synthesized and characterized using IR spectroscopy and elemental analysis. Crystal structure has been determined by XRD which reveals the pseudo octahedral complex geometry and the use of hydroxo bridges between two neighbor units to form a 1D coordination polymer. The use of this complex as a catalyst for the degradation of two textile dyes, in the presence of the appropriate amount of H2O2 and a UV light source has given very good results with yields exceeding 98% after 50 minutes.

单核铜络合物之字形链降解染料的研究
合成了具有四齿席夫碱配体[N,N ' -双(2-羟基-3-甲氧基苄基)-1,3-二氨基丙烯-2-醇]的单核配合物[Cu (L)],并用红外光谱和元素分析对其进行了表征。通过x射线衍射(XRD)测定了其晶体结构,揭示了伪八面体配合物的几何形状,并利用两个相邻单元之间的羟基桥形成了一维配位聚合物。用该络合物作为催化剂,在适量的H2O2和紫外光源的存在下,降解两种纺织染料,50分钟后收率超过98%,效果非常好。
