“…The previous small peaks become more significant. The spectral changes 3 and 7 d after the preparation of the solution confirm the occurrence of the nitro–nitrosyl conversion, and the reaction is still ongoing after 3 d. The reaction is accompanied by the shift of the nitro peak toward a range that is usual for coordinated nitro ligands in ruthenium–nitrosyl complexes , , . The presence of the free nitrite anion is revealed by a small peak at δ = 232.5 ppm; the intensities increase significantly for the peaks of the nitrosyl ligand at δ = –35.8 ppm and the ammine ligand in a trans ON–Ru–NH 3 arrangement at δ = –374.5 ppm.…”

Triammine fac and mer Coordination for Ruthenium–Nitrosyl Complexes: Synthesis and Characterization of [RuNO(NH₃)₃Cl₂]Cl

New high-yielding methods for two [RuNO(NH 3 ) 3 -Cl 2 ]Cl complexes are suggested. First, the ammine ligands are arranged facially through the reaction of a concentrated ammonia solution with the ruthenium-hexanitro complex. In the next step, the treatment of the previously unknown fac-Na[Ru(NO 2 ) 3 -(NH 3 ) 3 ]·3H 2 O with hydrochloric acid leads to the nitrosyl complex. The mer-[RuNO(NH 3 ) 3 Cl 2 ]Cl·H 2 O complex is formed from the corresponding aqua complex under reflux in 6 M HCl.[a] Nikolaev

“…This is logical since the donor atom in both ligands is nitrogen and both ligands have the same charge. The line belonging to the coordinated nitrate was observed in the range from –9.4 to –14.1 ppm in 14 N and 15 N NMR studies , , . However, the coordinated nitrate‐anion in the compound 1 shows up as the line at –21.8 ppm being shifted to the strong field.…”

“…In case of another popular class of starting nitrosyl complexes, nitrocomplexes, the cleavage of Ru/nitro bond occurs in the strongly acidic conditions, with heating, or in the presence of denitrification agents . We suggest nitrate complexes with low binding constants, as starting complexes for the design of nitrosyl ruthenium complexes with N ‐coordinated ligands. Substitution reactions of the coordinated nitrate‐anions should occur at mild conditions.…”

The reaction of nitrate ruthenium complex, fac-[RuNO(NH 3 ) 2 (NO 3 ) 3 ], with pyridine resulted in cis-[RuNO(NH 3 ) 2 Py 2 (NO 3 )](NO 3 ) 2 ·H 2 O with 84 % yield of the product at room temperature. Addition of any solvent leads to the reaction failure; the excess of pyridine fulfilled the role of a solvent. The DFT simulation of the dissociative mechanism reveals that the nitrate loss from cis-position to NO occurs more easily than for trans-coordinated nitrate. This conclusion is in agreement with the X-ray determined struc-* V. Vorobyev

Reaction of [RuNO(NO₂)₄OH]^2– with Sulfamic Acid as a Pathway to Mixed Nitro Pyridine Ruthenium Nitrosyl Complexes

et al. 2016

The transformations of [RuNO(NO2)4OH]2– during sequential treatment with sulfamic acid and pyridine have been investigated by 15N NMR spectroscopy. Depending on the initial molar ratio of Ru/NH2SO3H, the first stage of the reaction at room temperature in an aqueous solution proceeded with stoichiometric removal of one or two NO2 ligands and may be accompanied by ligand redistribution and partial isomerization NO2/ONO. Further treatment with pyridine resulted in the replacement of labile ligands (H2O, SO4) and the formation of mixed nitro pyridine complexes of ruthenium nitrosyl. Mixed nitrito‐N‐nitrito‐O complexes PyH[RuNO(NO2)2(ONO)Py(OH)] and OC‐6‐34‐[RuNO(NO2)(ONO)Py2OH] as well as the dimeric ruthenium complex with µ‐bridging oxo groups NH4[Ru(NO)Py3(µ‐O)]2(PF6)3 were separated as solids and structurally characterized. The photochemical isomerization (445 nm, 9 K) of Ru–NO with the formation of metastable isonitrosyl complexes was found for all the prepared compounds; the population of the metastable state did not exceed 20 %.
