Özet
[Ru(CO)(PPh3)2(η3-O,N3,S-TSC1)] (1), [Ru(Cl)(CO)(PPh3)2(η2-N3,S-TSC2)] (2), and [Ru(Cl)(CO)(PPh3)2(η2-N3,S-TSC3)] (3) have been prepared by reacting [Ru(H)(Cl)(CO)(PPh3)3] with the respective thiosemicarbazones TSC1 (2-hydroxy-3-methoxybenzaldehyde thiosemicarbazone), TSC2 (3-hydroxybenzaldehyde thiosemicarbazone), and TSC3 (3,4-dihydroxybenzaldehyde thiosemicarbazone) in a 1 : 1 M ratio in toluene and all of the complexes have been characterized by UV–vis, FT-IR, and 1H and 31P NMR spectroscopy. The spectroscopic studies showed that TSC1 is coordinated to the central metal as a tridendate ligand coordinating via the azomethine nitrogen (C=N), phenolic oxygen, and sulfur to ruthenium in 1, whereas TSC2 and TSC3 are coordinated to ruthenium as a bidentate ligand through azomethine nitrogen (C=N) and sulfur in 2 and 3. Oxygen sensitivities of 1–3 and [Ru(Cl)(CO)(PPh3)2(η2-N3,S-TSC4)] (4), and antimicrobial activities of 1–3 have been determined.
