The solid complexes of Pd(II) and Cd(II) with N,N/bis(salicylaldehyde)4,5-dimethyl-1,2-phenylenediamine (H2L(1)), and N,N/bis(salicylaldehyde)4,5-dichloro-1,2-phenylenediamine (H2L(2)) have been synthesized and characterized by several techniques using elemental analysis (CHN), FT-IR, (1)H NMR, UV-Vis spectra and thermal analysis. Elemental analysis data proved 1:1 stoichiometry for the reported complexes while spectroscopic data indicated square planar and octahedral geometries for Pd(II) and Cd(II) complexes, respectively. The prepared ligands, Pd(II) and Cd(II) complexes exhibited intraligand (π-π(∗)) fluorescence and can potentially serve as photoactive materials. Thermal behavior of the complexes was studied and kinetic parameters were determined by Coats-Redfern method. Both the ligands and their complexes have been screened for antimicrobial activities.
Pd(II)和 Cd(II)与 N,N/双(水杨醛)4,5-二甲基-1,2-苯二胺(H2L(1))和 N,N/双(水杨醛)4,5-二氯-1,2-苯二胺(H2L(2))的固体配合物已经通过元素分析 (CHN)、傅里叶变换红外光谱 (FT-IR)、(1)H NMR、紫外-可见光谱和热分析等多种技术进行了合成和表征。元素分析数据证明了所报道的配合物的 1:1 化学计量比，而光谱数据表明 Pd(II)和 Cd(II)配合物分别具有平面正方形和八面体几何构型。所制备的配体、Pd(II)和 Cd(II)配合物表现出内配体 (π-π(∗))荧光，并且可能可用作光活性材料。通过 Coats-Redfern 法研究了配合物的热行为，并确定了动力学参数。对配体及其配合物进行了抗菌活性筛选。
