Abstract
Reaction of dimers [M(η 5-C 5Me 5)Cl 2] 2 (M-Rh, Ir) with quinolin-8-ol in molar ratio 1:2 leads to formation of monomer complexes [Rh(η 5-C 5Me 5)Cl(qol)] ( 1) and [Ir(η 5-C 5Me 5)Cl(qol)] ( 2) (qol = quinolin-8-olate). Compounds 1 and 2 have been characterized with elemental analysis and spectroscopic methods. 1H NMR spectra revealed that quinolin-8-olate is coordinated via oxygen and nitrogen atoms. The 1H NMR and 13C NMR spectra showed that carbon and hydrogen atoms of pentamethylcyclopentadienyl ligand are equivalent. The structure of rhodium complex has been calculated using DFT B3LYP method. The calculated geometry of complex 1 agrees very well with data found for rhodium complexes containing Cl, C 5Me 5 and qol ligands. Both complexes are active antitumor and antibacterial agents.
