Abstract - Thiosemicarbazones have garnered significant
functional groups, allowing for fine-tuning of the ligand's electronic and steric properties [5]. Thiosemicarbazone ligands have demonstrated promising applications in the development of metal-based complexes for catalysis, bioinorganic chemistry, and medicinal chemistry [6] [7] . Their ability to form stable complexes with various metal ions makes them valuable tools for designing new materials and exploring their potential in different fields of research.
attention in scientific research due to their valuable properties as ligands, including optical, antibacterial, antifungal, anticancer activities, and more. By integrating these bioactive ligands with active metals, novel compounds with diverse properties can be synthesized. Bearing this in mind, we carried out a study to prepare ruthenium complexes using thiosemicarbazone ligands substituted with end substitution. Through characterization, we determined that the resulting ruthenium complexes exhibit an octahedral geometry, as revealed by our investigation.
Characterization techniques play a crucial role in understanding the structural and electronic properties of ruthenium Schiff base complexes. Elemental analysis provides information about the elemental composition of the complex, verifying the presence of ruthenium and other atoms within the complex. Spectroscopic techniques such as UV-Vis, and Infrared spectroscopy are employed to study the electronic transitions and vibrational modes of the complexes. These spectroscopic methods offer valuable insights into the bonding, coordination geometry, and electronic structure of the complexes [8] [9].
Key Words: Ruthenium, salal derivatives, spectroscopy, end substitution, ligand substitution.
1.INTRODUCTION The synthesis and characterization of ruthenium Schiff base complexes have gained considerable attention in recent years due to their significant potential in various fields of chemistry, including catalysis, materials science, and bioinorganic chemistry. Schiff base complexes are formed by the coordination of a metal center, such as ruthenium, with a Schiff base ligand. The Schiff base ligand is typically derived from the condensation reaction between an aldehyde and an amine.
In summary, the synthesis and characterization of ruthenium Schiff base complexes offer a fascinating avenue for exploring their structural, electronic, and reactivity properties. These studies contribute to the development of novel catalysts, functional materials, and bioinorganic systems with diverse applications in various scientific disciplines.
The synthesis of ruthenium Schiff base complexes involves the careful selection of appropriate ligand components and reaction conditions. The choice of aldehyde and amine precursors allows for the customization of the electronic, steric, and functional properties of the resulting complexes [1] [2]. The reaction is typically conducted under inert atmosphere conditions using suitable solvents and moderate temperatures.
2.EXPERIMENTAL All chemicals utilized in the study were of analytical reagent (AR) grade, and the solvents were purified and dried with standard procedures. The synthesis of metal starting complexes, [RuCl3(PPh3)3], [RuCl3(AsPh3)3], and Schiff base ligands are shown below. Elemental analyses (C, H, N & S) were conducted using a Vario EL III CHNS analyzer at STIC, Cochin University of Science and Technology, Kerala, India. IR and Magnetic moment values are recorded in our research laboratory.
Thiosemicarbazone ligands are a class of versatile molecules that have gained significant attention in coordination chemistry. These ligands possess a thiosemicarbazone functional group, which consists of a thioamide (-C=S) and a hydrazine (-NH-NH2) moiety [3] [4]. Thiosemicarbazone ligands offer a diverse range of coordination possibilities due to the presence of different substituents on the parent thiosemicarbazone backbone. These substituents can be modified to incorporate various
