Abstract
Some mononitrosyl complexes of transition metals exhibit one or two metastable states (linkage isomers, MS1 and MS2) when irradiated at low temperatures with appropriate wavelengths. In this work, the generation of metastable state one (MS1) (or Ru-ON linkage isomer) in K2[RuF5NO].H2O at 77 K was studied by sample excitation using laser light in a wide range of wavelengths. The effects of irradiation was monitored by infrared spectroscopy. ν(NO) in the ground state was shifted by -161 cm-1 when the complex was excited to MS1, a magnitude similar to that observed in other transition metal nitrosyls for a such state. We report on the excitation and deactivation of metastable states by using a wide variety of laser lines. A novel method for exploring the electronic structure of [RuF5NO]2- through the generation of MS1 is proposed. For this purpose, a sample was carefully irradiated with the same intensity of light for all laser lines in the spectral region 260-1064 nm. The integrated area under the ν(NO)MS1 band was used as a measure of MS1 population. The profile peaks of the MS1 population (ν(NO)MS1 band area) vs. the irradiation wavelength fit well with those of the electronic spectrum of the [RuF5NO]2- ion in an aqueous solution. The onset temperature for MS1 decay in K2[RuF5NO].H2O, at approximately 180 K, is slightly lower than the average reported for other ruthenium-nitrosyl systems.

Abstract
In general, the nitrosyl complexes of Mn(II)-porphyrinate having the {Mn(NO)}6 configuration are not considered as HNO or nitroxyl (NO-) donors because of [MnI-NO+] nature. A nitrosyl complex of Mn(II)-porphyrin, [Mn(TMPP2-)(NO)], 1 [TMPPH2 = 5,10,15,20-tetrakis-4-methoxyphenylporphyrin], is shown to release HNO in the presence of HBF4. It is evidenced from the characteristic reaction of HNO with triphenylphosphine and isolation of the [(TMPP2-)MnIII(H2O)2](BF4), 2. This is attributed to the fact that H+ from HBF4 polarizes the NO group whereas the BF4- interacts with metal ion to stabilize the Mn(III) form. These two effects cooperatively result in the release of HNO from complex 1. In addition, complex 1 behaves as a nitroxyl (NO-) donor in the presence of [Fe(dtc)3] (dtc = diethyldithiocarbamate anion) and [Fe(TPP)(Cl)] (TPP = 5,10,15,20-tetraphenylporphyrinate) to result in [Fe(dtc)2(NO)] and [Fe(TPP)(NO)], respectively.

Abstract
![]()
Ruthenium 4d-to-2p
X-ray emission spectroscopy (XES) was systematically
explored for a series of Ru2+ and Ru3+ species.
Complementary density functional theory calculations were utilized
to allow for a detailed assignment of the experimental spectra. The
studied complexes have a range of different coordination spheres,
which allows the influence of the ligand donor/acceptor properties
on the spectra to be assessed. Similarly, the contributions of the
site symmetry and the oxidation state of the metal were analyzed.
Because the 4d-to-2p emission lines are dipole-allowed, the spectral
features are intense. Furthermore, in contrast with K- or L-edge X-ray
absorption of 4d transition metals, which probe the unoccupied levels,
the observed 4p-to-2p XES arises from electrons in filled-ligand-
and filled-metal-based orbitals, thus providing simultaneous access
to the ligand and metal contributions to bonding. As such, 4d-to-2p
XES should be a promising tool for the study of a wide range of 4d
transition-metal compounds. Ruthenium 4d-to-2p
XES was applied to a series of molecular
Ru complexes with varied coordination environment, oxidation state
and site symmetry. Through correlations to calculations, it is demonstrated
the Ru 4d-to-2p XES provides a unique probe of both the filled ligand np and filled metal 4d orbitals, providing a promising new
tool for the study of a wide range of 4d transition metals.

Abstract
Photodelivery of NO requires stable compounds which can be made reactive by irradiation with (visible) light. Traditional {MNO}6 complexes require a substantial ligand design to shift their absorption spectra to the appropriate region of the electromagnetic spectrum. [Fe((CH2Py2)2Me[9]aneN3)(NO)](BF4)2 is a new {FeNO}7 octahedral coordination compound, which is thermally and air-stable in solution. Illumination with a 450 nm light source induces significant photodetachment of the coordinated NO (ϕNO = 0.52 mol einstein-1), suggesting that {FeNO}7 compounds can be in fact suitable compounds for therapeutic NO-photorelease.

Nitrosodisulfide S2NO- is a controversial intermediate in the reactions of S-nitrosothiols with HS- that produce NO and HNO. QM-MM molecular dynamics simulations combined with TD-DFT analysis contribute to a clear identification of S2NO- in water, acetone and acetonitrile, accounting for the UV-Vis signatures and broadening the mechanistic picture of N/S signaling in biochemistry.

Abstract
Hydrogen sulfide (H2S) and nitric oxide (NO) are important signaling molecules that regulate several physiological functions. Understanding the chemistry behind their interplay is important for explaining these functions. The reaction of H2S with S-nitrosothiols to form the smallest S-nitrosothiol, thionitrous acid (HSNO), is one example of physiologically relevant cross-talk between H2S and nitrogen species. Perthionitrite (SSNO(-)) has recently been considered as an important biological source of NO that is far more stable and longer living than HSNO. In order to experimentally address this issue here, we prepared SSNO(-) by two different approaches, which lead to two distinct species: SSNO(-) and dithionitric acid [HON(S)S/HSN(O)S]. (H)S2NO species and their reactivity were studied by (15)N NMR, IR, electron paramagnetic resonance and high-resolution electrospray ionization time-of-flight mass spectrometry, as well as by X-ray structure analysis and cyclic voltammetry. The obtained results pointed toward the inherent instability of SSNO(-) in water solutions. SSNO(-) decomposed readily in the presence of light, water, or acid, with concomitant formation of elemental sulfur and HNO. Furthermore, SSNO(-) reacted with H2S to generate HSNO. Computational studies on (H)SSNO provided additional explanations for its instability. Thus, on the basis of our data, it seems to be less probable that SSNO(-) can serve as a signaling molecule and biological source of NO. SSNO(-) salts could, however, be used as fast generators of HNO in water solutions.
