Abstract: First example of a nitrosoruthenium complex with a nitroxyl radical is prepared by the interaction of Na2RuNOCl5 with 2-(3-pyridyl)-4,4,5,5-tetramethyl-4,5-dihydro-l-H-imidazole-1-oxyl-3-N-oxide (L) in acetonitrile at 85°C. The reaction product is the Na[RuNOCl4L] monosubstituted complex where the nitroxyl radical is coordinated by the nitrogen atom of the pyridine ring and occupies a cis position with respect to the nitroso group. The EPR data show that the spin density distribution in the radical almost does not change upon the coordination. The combination of electronic spectroscopy and density functional theory (DFT) data show that transitions at 500-700 nm are determined by the intraligand electron transfer in the nitroxide radical and by the electron transfer from the nitroxyl radical to the orbitals of the Ru–NO fragment.
