Two isomers, [Ru(1)]2+ (Ru = Ru(bpy)2, bpy = 2,2'-bipyridine, 1 = 2-(pyrid-2'-yl)-1-azaacridine) and [Ru(2)]2+ (2 = 3-(pyrid-2'-yl)-4-azaacridine), are bioinspired model compounds containing the nicotinamide functionality and can serve as precursors for the photogeneration of C-H hydrides for studying reactions pertinent to the photochemical reduction of metal-C1 complexes and/or carbon dioxide...

The present work describes the robust synthesis of Ru alkylidene complexes (PCy(3))(2)Cl(2)Ru=CHR - precursors for metathesis catalysts. Moreover, the dynamic behavior of complexes where R = 2-naphthyl and 2-thienyl was studied. (1)H NMR techniques were employed to establish the preferred conformations in solution for both complexes and the energy barrier for rotation around single (Ru=)CH-C(th...

The title triangulo-triruthenium(0) compound, [Ru(3)(C(30)H(32)P(2))(CO)(10)], contains a triangle of singly bonded Ru atoms. The phosphane-bridged Ru-Ru distance [2.9531 (2) Å] is significantly longer than the non-bridged Ru-Ru distances [2.8842 (2) and 2.8876 (2) Å] . The bis-(diphenyl-phosphan-yl)hexane ligand bridges the Ru-Ru bond. Each phosphane-substituted Ru atom bears one equatorial an...

The first example for an endohedral transition-metal atom (Ru) sequestered in a seven-coordinate surrounding of rare-earth metal atoms (Pr) has been found for {RuPr3}Cl3. The monocapped trigonal prisms of Pr atoms share two rectangular faces, forming a zigzag chain with Ru-Ru distances of 308 pm. Intracluster bonding is dominated by Ru-Pr bonding with very little Ru-Ru bonding.

A new lipophilic Ru salen complex with cholesterol groups can be efficiently incorporated into liposome bilayers, allowing the photoinduced release of nitric oxide (NO) and the membrane transport of NO to coexisting liposomes.

Insight into how H2 O is oxidized to O2 is envisioned to facilitate the rational design of artificial water oxidation catalysts, which is a vital component in solar-to-fuel conversion schemes. Herein, we report on the mechanistic features associated with a dinuclear Ru-based water oxidation catalyst. The catalytic action of the designed Ru complex was studied by the combined use of high-resolut...

Ruthenium (Ru) doped lithium niobate (LiNbO3) single crystal was grown by the Czochralski method from a congruent melt composition. The color of the Ru: LiNbO3 was red and darkened with the increasing Ru concentration. The amount of Ru concentrated in the grown crystal gradually decreased along the pulling direction because the effective segregation coefficient of Ru in lithium niobate is great...

We report the synthesis and characterization of new Ni(x)Ru(1-x) (x = 0.56-0.74) alloy nanoparticles (NPs) and their catalytic activity for hydrogen release in the ammonia borane hydrolysis process. The alloy NPs were obtained by wet-chemistry method using a rapid lithium triethylborohydride reduction of Ni(2+) and Ru(3+) precursors in oleylamine. The nature of each alloy sample was fully chara...
