Mixed ruthenium(II) nitrosyls have been synthesized in yields larger than 60percent by a general reaction of 5-C5H5)(PPh3)L>+X- (L = 2,2'-bipyridine or 1,10-phenanthroline, X- = Cl- or Br-) or 5-C5H5)(PPh3)(L)X> (L = PPh3, pyridine, 3-picoline, 4-picoline, 1/2(2,2'-bipyridine), or 1/2(1,10-phenanthroline); 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 ?-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, 1H nmr spectral data.
