Mixed ruthenium(II) nitrosyls have been synthesized in yields larger than 60% by a general reaction of [Ru(η5-C5H5)(PPh3)L]+X− (L = 2,2′-bipyridine or 1,10-phenanthroline, X = Cl or Br) or [Ru(η5-C5,H5)(PPh3)(L)X] (L = PPh3, pyridine, 3-picoline, 4-picoline, [Formula: see text], or [Formula: see text]; X− = Cl−, Br−, I−, CN−, NCS−, H−, or SnCl3−) with NOBr3 and N2O3. In these complexes NO seems to bind with the metal ion as NO+. The reactions of N2O3 gave either nitrito or nitrosyl dinitrito complexes. The reactions of NOBr3 with trichlorostannate complexes did not yield nitrosyl complexes, instead nitrito complexes were isolated in which spectroscopic evidence (ir, 1H nmr) suggest π-interaction of one of the phenyl rings of the triphenylphosphine ligand to the ruthenium center. All products are characterised by elementary microanalyses, conductivity, magnetic moment measurements, electronic, ir, and 1H nmr spectral data.

Hydride Complex

Treatment of RuCl(dppm)(η5-C9H7) with alkynes HC≡C(C6H4)nC≡CH (n = 1, 2) in the presence of TlPF6 and t-BuONa affords the bimetallic ruthenium acetylide complexes [(η5-C9H7)(dppm)Ru]2(µ-C≡C(C6H4)nC≡C). Reactions of the hydride complex RuH(dppm)(η5-C9H7) with HC≡C(C6H4)nC≡CH (n = 1, 2) in refluxing toluene give the bimetallic ruthenium alkenyl complexes [(η5-C9H7)(dppm)Ru]2(µ-CH=CH(C6H4)nCH=CH). The electrochemical properties of the new complexes have been investigated by cyclic voltammetry, which reveals that the organic spacer –CH=CHC6H4CH=CH– is more effective than –C≡CC6H4C≡C– in mediating electronic communication between the two ruthenium moieties.Key words: ruthenium, bimetallic, acetylide, insertion, electrochemistry.

<div>Spectroscopic evidence is presented to show that NADH in aqueous solution does not exist as a folded/unfolded equilibrium but as a single state. The molecule is folded but without base stacking between dihydronicotinamide and adenine.<br></div>
