The mechanism of the acid-catalyzed hydrolysis of (NH<SUB>3</SUB>)<SUB>5</SUB>RuO<SUB>2</SUB>CR<SUP>2+</SUP> (R=H, CH<SUB>3</SUB>, C<SUB>2</SUB>H<SUB>5</SUB>, (CH<SUB>3</SUB>)<SUB>2</SUB>CH, CH<SUB>2</SUB>OH, and/or CH<SUB>2</SUB>NH<SUB>2</SUB>) has been established by the trapezoidal simulation analyses with a computer. The proposed reaction sequences of <I>S</I><SUB>N</SUB>1 combined with <I>S</I><SUB>N</SUB>2 mechanisms involving a quasi-stable intermediate (NH<SUB>3</SUB>)<SUB>5</SUB>Ru<SUP>3+</SUP> have proved to be plausible, and the kinetic parameters (rate constants, <I>ΔH</I><SUP>\neweq</SUP>, <I>ΔS</I><SUP>\neweq</SUP>, <I>etc.</I>) have been given for all of the elementary reactions. The aquation rate has been determined by the solvent-assisted, heterolytic dissociation of (NH<SUB>3</SUB>)<SUB>5</SUB>RuO<SUB>2</SUB>CR<SUP>2+</SUP> and follows this order: formato>acetato>propionato>isobutyrato>glycolato>glycinato.
