Synthesis, Spectroscopic Characterization and Antibacterial Activity of some Chloro Dimethylsulphoxide/ Tetramethylenesulphoxide Ruthenium (II)/(III) Complexes with 1, 2, 3-Benzotriazole.
Synthesis and characterization of seven ruthenium (II) and ruthenium (III) chloro sulphoxide complexes with 1, 2, 3-benzotriazole are reported. Three different formulations exist: [cis, fac-RuCl2(so)3(btz)]; [trans-RuCl2(so)3(btz)] and [trans-RuCl4(so)(btz)]-[X]+; where so=dimethylsulphoxide/ tetramethylenesulphoxide; btz = 1, 2, 3-benzotriazole and [X]+ = [(btz)H]+ or Na+. These complexes were characterized by elemental analysis, conductivity measurements, magnetic susceptibility, FT-IR, 1H-NMR, 13C1H-NMR and electronic spectroscopy. Complexes were screened for their antibacterial activity and found more potent than 1, 2, 3-benzotriazole ligand and precursor ruthenium compounds against gram-negative bacteria Escherichia coli. All the samples were compared with antibiotic Chloramphenicol for reference.
