Ruthenium brown

Fig. 7.32 Mossbauer spectra of (i) ruthenium red, [Ru302(NH3)i4]Cl6 and (ii) ruthenium brown, [Ru302(NH3)i4]Cl7, fitted with a side-by-side (a) and an overlapping (b) arrangement of two quadrupole patterns (from [116])...

Oxidation of [Ru302(NH3)i4] or [Ru302(NH3),o(en)2f with HCl in air, or by CI2 water gives the [4,3,4] " analogue ruthenium brown. Mossbauer studies on the 6-H and 7-1- ions are in agreement with linear structures for these complexes. The resonance Raman spectra of ruthenium red and brown and of their en analogues have been reported. Ruthenium brown is reduced by OH in a second order reaction with rate constant k = 1.9 x 10 s mol , = 79.5kJmol ,... [Pg.321]

Several related papers have appeared concerning the facile oxidation of hydroxide ion by ruthenium brown via equation (10). Kinetic results are consistent with a mechanism involving rate-determining attack of OH on the... [Pg.349]
