ruthenium arene complexes; 7,8-benzoquinoline; 8-hydroxyquinoline X-ray structure; TDDFT method
The reaction of [(C6H6)RuCl2](2) with 7,8-benzoquinoline and 8-hydroxyquinoline in methanol were performed. The obtained complexes have been studied by IR, UV-VIS, H-1 and C-13 NMR spectroscopy and X-ray crystallography. In the reaction with 8-hydroxyquinoline the arene ruthenium(II) complex oxidized to Ru(III). The electronic spectra of the obtained compounds have been calculated using the TDDFT method. Magnetic properties of [Ru(C9H6NO)(3)] (.) CH3OH complex suggest the antiferromagnetic coupling of the ruthenium centers in the crystal lattice. EPR spectrum of [Ru(C9H6NO)(3)] (.) CH3OH compound indicates single isotropic line only characteristic for Ru3+ with spin equal to 1/2. (c) 2005 Elsevier Ltd. All rights reserved.
