Absence of common five-co-ordinate intermediates in the induced reactions of some cobalt(III)–acido complexes

The stereochemistry of the aqua and hydroxo products fromed in the induced aquation (Hg²⁺, Ag⁺, NO⁺) and base hydrolysis reactions of anti-p, syn-p, and s-[Co(Metren)NH₃X]ⁿ⁺ ions (n= 2 or 3; tren = 2,2′,2″-triaminotriethylamine; X = Cl, Br, N₃, NH₃; p = primary, s = secondary) show a dependence on leaving group, type of reaction, and reactant stereochemistry, thereby eliminating the formation of common intermediates.
