N2  - The anation reactions:                        Cr(Me2SO)63+ + X- &#8594; CrX(Me2SO)52+ + Me2SO   have been studied in detail for X- = N3- and SCN- as a function of concentration, temperature and ionic strength in both conditions of X- in excess over Cr(Me2SO)63+, and Cr(Me2SO)63+ in excess over X-, where greater certainty exists concerning the nature of the solution species. The reactions are interpreted as dissociative interchange reactions in which anation is a probable result of dissociation only when the anion occupies a position in the first solvation sphere of the complex.     Less complete results are presented for the less tractable anation of Cr(Me2SO)63+ by Cl- in Me2SO, and the analogous reaction of Cr(HCONMe2)63+ by Cl- in dimethylformamide.
