The reaction of [(C 6 H 6 )RuCl 2 ] 2 with 7,8-BENZOQUINOLINE (cas 230-27-3) and 8-hydroxyquinoline in methanol were performed. The obtained complexes have been studied by IR, UV–VIS, 1 H and 13 C 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(C 9 H 6 NO) 3 ]·CH 3 OH complex suggest the antiferromagnetic coupling of the ruthenium centers in the crystal lattice. EPR spectrum of [Ru(C 9 H 6 NO) 3 ]·CH 3 OH compound indicates single isotropic line only characteristic for Ru 3+ with spin equal to 1/2.
