Reactivity of coordinated nitrosyls. 6. Preparation, characterization and reduction of nitrosylpentaaquoruthenium(3+) and reduction of various ruthenium ammine nitrosyls

Redox-catalyzed aquation of nitrosylpentaammineruthenium(3+) ion

“…[Ru(NH3)5NO]C13 was prepared by the reaction of Ru(NH3)63+ with NO(g)10 or by the method of Gleu.11 The TFMS" salt was prepared as previously described. 4 Both the Cl" and TFMS" salts gave identical results in this study. The preparation of trans-[Ru-(NH3)4NO(OH)]Cl2 has been described before.11 Solutions of the Ru complexes containing HC02" as the only anion were prepared from the Cl" salts using ion-exchange techniques.…”

Reatividade química e fotoquímica de complexos nitrosilos de rutênio do tipo [Ru(terpy)(L)NO]n+

“…• Borbulhamento de NO gasoso em uma solução aquosa de uma espécie precursora que contenha o fragmento Ru III -H2O (CHENEY & ARMOR, 1977;NAGAO et al, 1989). Neste caso, o ligante nitrosil coordena-se preferencialmente provocando a redução do metal e formando o fragmento estável {Ru II -NO + }.…”
