Abstract: Ruthenium (Ru) and its complex have immense importance in coordination chemistry because of their active applications in bioinorganic chemistry, organometallic chemistry, catalysis, etc. Here, this study will discuss the synthesis of surface-functionalized gold nanoparticles (AuNPs) attached to Ru metal using tetrazine as the bridging ligand. AuNPs have been prepared by slightly modifying the ‘Brust’ two-phase synthesis method. The Ru complexes have been prepared by the reaction of 6-(3,5-dimethyl-1H-pyrazol-1-yl)-1,2,4,5-tetrazin-3-amine (amtz) with dimeric precursor complex [(p-cym)RuCl(μ-Cl)2 (p-cym = 1-isopropyl-4methylbenzene)] in methanol. The attachment of the complex on the AuNPs surface has been confirmed by UV-Visible (UV-Vis) spectroscopy. The surface plasmon band that appeared at 523 nm indicates the stability of AuNPs functionalized with Ru complex in the solution.
