Abstract
We find an unusual example in which different clusters can be isolated from the same reaction mixture depending on the choice of counter-ion. The complex [(bipy)2Mn(III)(μ-O)2Mn(IV)(bipy)2]3+ (1) (bipy=2,2′-dipyridyl) is isolated from Mn(II) and permanganate in acetate buffer with ClO4 -, but [(bipy)(H2O)Mn(III)(μ-O)(μ-OAc)2Mn(III)(bipy)(H2O)]2+ (2) with NO3 -. 1e-/2H+ or 1e-/1H+ proton-coupled electron transfer chemistry is found for 2 according to the type of buffer used. The new complex [(bipy)(H2O)Mn(III)(μ-O)2(μ-OAc)Mn(IV)(bipy)(H2O)]2+ (3) is also postulated as an intermediate in the formation of 1.
