The structure of the nitrosyl [RuCl3(NO)(AsPh3)2] complex

Nitric Oxide Photorelease from Ruthenium Salen Complexes in Aqueous and Organic Solutions

“…The bond distances Ru−NO and N−O for the chloro complex are in accordance with those found for other ruthenium nitrosyl complexes − such as [Ru(NO)(OH)(bpy)(py) 2 ] 2+ , 1.724(7) and 1.152(9) Å, trans -[RuCl(NO) (cyclam)] 2+ , 1.747(4) and 1.128(5) Å, and [RuCl 3 (NO)(AsPh 3 ) 2 ], 1.729(7) and 1.151(9) Å . The relatively short bonds Ru−NO and N−O and the Ru−N−O angle not distorted greatly from linearity are indicative of a multiple bond between Ru(II) and nitrosonium (NO + ) and not of a single bond between Ru(III) and nitrosyl (NO).…”

Ruthenium chalcogenonitrosyl and bridged nitrido complexes containing chelating sulfur and oxygen ligands

“…Selected bond lengths and angles of 1, 2 and related nitrido 26 and nitrosyl 27 complexes are listed in Table 1 for comparison. 27 :ν(N-S) ratio of 1.43 is similar to those of reported systems (1.40-1.47) 10,18,30 and significantly higher than the harmonic oscillator approximation(1.14) based on the reduced mass of NO and NS. This result is supportive of stronger N-X interaction in the nitrosyl complex (M=N=O) compared with that in the thionitrosyl congener that features a donor-acceptor interaction between M≡N and S. 18 By contrast, the ν(N-S):ν(N-Se) ratio (for 1 and 2) of 1.1 agrees well with the harmonic oscillator approximation, indicating similar N-X bonding in the NS and NSe complexes.…”

The Ru-N distances in 1 [1.753(4) Å] and 2 covalent double bonds, whereas the N-X bonding in the M(NX) (X = S, Se) analogues can be considered as donor-acceptor interactions between MuN and the X atom in the singlet state with two filled pπ orbitals (Scheme 3).…”
