Abstract:
Three ligands L', L2, L3 and their corresponding organometallic ruthenium complexes Ru(PPh3)2L'hCl (n = 1 — 3) have been synthesized and characterized IR spectroscopy, GC-MS, UV-Vis spectrophotometry, NMR spectroscopy. Reactivity of nitric oxide was investigated with these three complexes. The resultant ruthenium nitrosyl complexes Ru(PPh3)2L(NO) were characterized by IR spectroscopy, UV-Vis spectrophotometry, 1H, 13C and 31P NMR spectroscopy. Interaction of visible light was investigated with these ruthenium nitrosyl complexes and ligated NO was speculated to be photolabile. The photoreleased NO has been trapped by reduced myoglobin
