“…As the nature of this ligand changes, a shift of more than 100 cm –1 for the nitrosyl stretching frequency is observed. Electron donor ligands (OH – , halide ions, and phosphate) shift the NO vibration band to lower energy (under 1900 cm –1 ). Conversely, with lower electron donor ligands (NH 3 , pyridine, imidazole, H 2 O, and NO 3 ) the nitrosyl vibration band is observed at wave numbers >1900 cm –1 .…”

“…The synthesis of ruthenium–nitrosyl complexes with trans ON–Ru–NH 3 arrangements is a difficult task. The reported methods describe synthetic pathways for pentaammine, or cis ‐tetraammine ruthenium–nitrosyl complexes in aqueous solutions . The problem arises from the instability of the ammine ligand coordinated trans to the NO ligand in basic media.…”

“…The problem arises from the instability of the ammine ligand coordinated trans to the NO ligand in basic media. A hydroxido ligand tends to replace the ammine ligand or cis ‐to‐ trans isomerization occurs for tetraammine complexes . Thus, the way to synthesize these complexes is to attach a nitrosyl ligand to the already prepared ammine complexes.…”

“…The evidence suggests that tra«5-Ru(NH3)4(0H)N02+ is formed via reaction 9 by cleavage of the Ru to imine bond, which is weakened by the competition of the imine and NO+ ligands for the same Ru(II) orbitals. Substitution by OH" then completes the reaction.…”
