A series of palladium complexes of tetradendate Schiff base ligands L1 (N,N′-bis(salicylidene)phenylene-1,3-diamine) and its derivatives L2 and L3 have been synthesized by using the “flexible ligand method” within the supercage of zeolite-Y. These complexes in both their free and encapsulated states have been thoroughly characterized with the help of different characterization tools such as XRD, SEM-EDS

of La(III), Er(III) and Yb(III) chlorides with H2L. The ligand and complexes were characterized using elemental analysis, infrared, 1H NMR, UV–visible and mass spectroscopies, magnetic susceptibility and conductivity measurements and thermal analysis. Infrared and 1H NMR spectra indicated the coordination of the azomethine nitrogens and deprotonated phenolic oxygen atoms in a tetradentate manner (ONNO)
一种新颖的席夫碱配体,即2,2' - ((1- Ë,1' ë) - (1,3-亚苯基二(azanylylidene))双(methanylylidene))联苯酚(H 2 L),通过的缩合合成米-苯二胺和2-羟基苯甲醛(以1:2的比例)。从La(III),Er(III)和Yb(III)氯化物与H 2 L的反应中获得了一系列配合物。配体和配合物的特征在于元素分析,红外光谱,1 H NMR,紫外可见光和质量光谱学,磁化率和电导率测量以及热分析。红外和11 H NMR谱表明偶氮甲氮和去质子化的酚氧原子以四齿态(ONNO)配位。研究了从环境温度到1000°C的配合物的热行为。发现该配合物具有水合水分子和配位水分子。与游离配体(革兰氏阳性细菌金黄色葡萄球菌和枯草芽孢杆菌,革兰氏阴性细菌沙门氏菌,大肠杆菌和铜绿假单胞菌和真菌烟曲霉和白色念珠菌)相比,该复合物对各种生物具有较高的生物活性。)。使用分子对
