Laser flash excitation of 1/1 ion pairs consisting of the reversible redox systems [M(mnt)2]2- (mnt2- = maleonitriledithiolate) and V(n+) (V = 2,2'- or 4,4'-bipyridinium derivative, n = 2,1) affords the electron-transfer products [M(mnt)2]- and V(n-1)+ in the case of M = Pt, while no transients are observed when M = Ni. These primary redox products recombine by a fast second-order back-reaction. The cage escape efficiencies are very sensitive to the charge of the quenchers (1.0 for n = 1, 0.1 for n = 2). The back-electron-transfer rate constants are close to the diffusion-controlled values and seem to depend slightly on the driving force.
