A presença do grupo -NH2 confere a ela uma habilidade em se coordenar a diferentes íons metálicos. Neste trabalho foram sintetizado 3 novos complexos metálicos de Au(I), Ag(I) e Pd(II) com rimantadina. Os complexos foram preparados pela reacão de solucões aquosas ou alcoólicas da rimantadina com os respectivos sais de Au(I), Ag(I) e Pd(II). Os compostos foram caracterizados por um conjunto de análises químicas e espectroscópicas, bem como através de cálculos de Density Functional Theory (DFT). Os espectros no infravermelho (IV) e de ressonância magnética nuclear (RMN) da rtd livre e dos complexos indicaram a coordenação da rtd aos íons metálicos através do átomo de nitrogênio do grupo NH2. Os compostos foram analisados quanto as suas atividades biológicas antibacteriana sobre cepas de bactérias Gram-positivas e Gram-negativas. Os resultados mostraram que os complexos de Au(I) e Ag(I) são ativos sobre cepas de Staphylococcus aureus, Pseudomonas aeruginosa e Escherichia coli / Abstract: Rimantadine (C12H21N - rtd) is a antiviral agent which inhibit specifically the replication of the virus influenza A. The presence of group -NH2 confers the ability to coordinate with different metal ions. In this work 3 novel metal complexes of Au(I), Ag(I) e Pd(II) with rimantadine were synthesized. The complexes were prepared by the reaction of aqueous or alcoholic solutions of rimantadine with the respective salts of Au(I), Ag(I) e Pd(II). The compounds were characterized by a set of chemical and spectroscopic analyses, also by Density Functional Theory (DFT) studies. The infrared (IR) spectra and nuclear magnetic resonance (NMR) of the free rtd and of the compounds indicate the coordination of rtd to metallic ions through the nitrogen atom of group NH2. The compounds were analyzed concerning their antibacterial activities against Gram-positive and Gram-negative bacterial strains. The results showed that the Au(I) and Ag(I) complexes are active against Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli strains / Mestrado / Quimica Inorganica / Mestra em Química
