VO(II), Ni(II), Pd(II), Pt(IV) and UO2(II) complexes were prepared using H5L ligand (C21H15N9S2O3S2). All the prepared complexes are deliberately discussed using different tools(IR, Uv-Vis, 1HNMR, ESR 13CNMR, TGA, TEM, XRD).The octadentate is the main mod of ligand donation, as a neural or trinegativetowards the metal ion. This is verified using molecular modeling as a theoretical tool assert on the stereo structure of the ligand proposed leads to the donation mod. The structural formulas of the complexes were varied in between four to six coordination no. except the VO(II) complex is five. Most investigated complexes are thermally unstable due to the presence of crystal water occluded the coordinating crystal. All the spin Hamiltonian parameters as well as molecular orbital parameters were calculated for VO(II) complex. XRD patterns were investigated to calculate the particle size of each compound and display their nanosized by distinguish values. TEM scenes are also supporting the XRD data. Finally the biological activities were carried out on different bacteria as well as on fungi. The toxic effect was observed especially with Gram positive bacterium (Bacillus subtilis). Also, the effect on DNA degradation was recorded and display a complete degradation by the use of Pt(IV) and Pd(II) complexes. Whereas, a partial degradation was observed with Ni(II) and UO2(II) complexes. But, there is no effect observed with the use of ligand and VO(II) complex.
使用 H5L
配体 (
C21H15N9S2O3S2) 制备 VO(II)、Ni(II)、Pd(II)、Pt(IV) 和 UO2(II) 配合物。使用不同的工具(IR、Uv-Vis、1HNMR、ESR 13CNMR、TGA、
TEM、XRD)对所有制备的配合物进行了仔细的讨论。八齿酸是
配体供给的主要模式,作为对
金属离子的神经或三负性。使用分子模型作为理论工具验证了这一点,断言所提出的
配体的立体结构导致了捐赠模式。配合物的结构式在四到六个配位之间变化。除了 VO(II) 复合体是 5 之外。由于结晶
水的存在封闭了配位晶体,大多数研究的配合物都是热不稳定的。计算了 VO(II) 络合物的所有自旋哈密顿参数以及分子轨道参数。研究 XRD 图案以计算每种化合物的粒径并通过区分值显示其纳米尺寸。
TEM 场景也支持 XRD 数据。最后对不同的细菌和真菌进行了
生物活性研究。特别是对革兰氏阳性细菌(
枯草芽孢杆菌)观察到毒性作用。此外,还记录了对 DNA 降解的影响,并显示使用 Pt(IV) 和 Pd(II) 复合物的完全降解。然而,Ni(II) 和 UO2(II) 络合物观察到部分降解。但是,使用
配体和 VO(II) 络合物没有观察到效果。
