The nitrosylation of RuCl3·(H2O)(x) in thionyl chloride affords anhydrous [RuCl3(NO)] which, when treated with a variety of ligands L, gives [RuCl3(L)2(NO)]. For L = 3,5-dimethylpyrazole (dmpH) it is possible to isolate and characterize the corresponding monomeric complex 1 as well as unusual oxo bridged dimeric products with nitrosyl ligands trans to the oxo ligand with either a linear geometry, as in trans O[RuCl2(NO)(dmpH)2] (2) and [Cl4(NO)Ru]O[Ru-(NO)(dmpH)4] (4), or with a bent geometry, as in trans O[RuCl(NO)(dmpH)(μ-dmp)]2 (3). These compounds have been characterized by elemental analysis and vibrational and NMR spectroscopy, as well as by single crystal X-ray diffraction. Collectively the structural and spectroscopic data support a delocalized π-bonding model across the linear ON-Ru-O-Ru-NO framework.

Light-induced NO release based on exogenous NO donors has attracted substantial attention in clinical applications; the induction light source usually converts near-infrared light to blue or ultraviolet light. However, the low efficiency of near-infrared light-assisted chemical light energy conversion remains a challenge, especially for NaYF4:Yb3+/Tm3+ photoconverting near-infrared light to ultraviolet (UV) and blue light. In this paper, a luminescence-enhanced strategy is reported by doping Ca2+ into NaYF4:Yb3+/Tm3+ and coating it with NaGdF4 through a two-step solvothermal method. Then, UCNPs modified with methyl-β-cyclodextrin (M-β-CD) are loaded on a ruthenium nitrosyl complex [(3)Ru(NO)(Cl)] as nitric oxide release-molecules (NORMs). X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS) data demonstrated that Ca2+ was successfully doped into NaYF4:Yb3+/Tm3+ nanoparticles as the core, and a pure hexagonal phase, NaYF4, was obtained from the doping of Ca2+. TEM revealed that the crystallinity was significantly improved after Ca2+ doping, and the core-shell structure was successfully synthesized, with NaGdF4 directionally grown on the NaYF4:Ca/Yb/Tm core. Fluorescence tests showed that, especially in the ultraviolet and blue light excitation wavelength regions, the UC emission intensity of the Ca-doped NaYF4:Yb3+/Tm3+?NaGdF4 core-shell UCNPs increased by 302.95 times vs. NaYF4:Yb3+/Tm3+ UCNPs. Finally, the release of NO was tested by the Griess method. Under 980 nm irradiation, the cell viability distinctly decreased with increasing UCNPs?M-β-CD-NORMs concentration. This study shows that NORM release of NO is triggered by enhanced up-converted UV and blue light, which can be used for the development of UV photo-sensitive drugs. This journal is
