Abstract

The present study was aimed to synthesize and characterize monometallic complex of Cu(II) using different diamines, i.e., 4-chloro-1,2-phenylenediamine and 4-fluoro-1,2-phenylenediamine, in the presence of CuCl₂ to form complexes of the type [Cu(C₁₂H₁₄N₄Cl₂)]Cl₂ and [Cu(C₁₂H₁₄N₄FCl)]Cl₂. These synthesized complexes were further treated with organotin dichlorides (R₂SnCl₂), where R = CH₃ and C₆H₅ for the synthesis of heterobimetallic complexes. The complexes have been synthesized using both conventional and microwave heating techniques. The complexes synthesized have been further characterized by elemental analysis, infrared spectra, electronic spectra, ESR, conductance measurement, mass spectra and X-ray powder diffraction studies. On the basis of these studies, distorted octahedral geometry has been proposed for the heterobimetallic complexes synthesized by utilizing monometallic complexes. The newly synthesized complexes have been screened for their antimicrobial activity. The results obtained were compared with the standards used during antifungal and antibacterial activity (i.e., Bavistin and Streptomycin). The pesticidal activity of these complexes was also evaluated against nymph and adult species of Chrotogonus trachypterus by taking into consideration their mortality rate.

铜（II）异双金属配合物的微波辅助合成，结构解析，抗菌和杀虫活性

摘要

本研究的目的是使用不同的二胺，即，4-氯-1,2-苯二胺和4-氟-1,2-苯二胺，以合成和表征单金属配合物的Cu（II），在CuCl存在下₂到形式[Cu（C ₁₂ H ₁₄ N ₄ Cl ₂）] Cl ₂和[Cu（C ₁₂ H ₁₄ N ₄ FCl）] Cl _{2型配合物}。这些合成的配合物进一步用二氯化有机锡（R ₂ SnCl ₂）处理，其中R = CH ₃和C ₆ H ₅用于合成异双金属配合物。已经使用常规和微波加热技术合成了配合物。通过元素分析，红外光谱，电子光谱，ESR，电导测量，质谱和X射线粉末衍射研究进一步表征了合成的配合物。在这些研究的基础上，提出了利用单金属配合物合成的异双金属配合物的八面体形畸变。已经筛选了新合成的复合物的抗微生物活性。将获得的结果与抗真菌和抗菌活性期间使用的标准品（即Bavistin和Streptomycin）进行比较）。还考虑了它们的死亡率，评估了这些配合物对若虫和成年种对虾的致病性。
