  The 2E excited states trans-[*Cr([14]aneN4)(NH3)2]3+ and trans-[*Cr([14]aneN4)(CN)2]+ oxidize methyl viologen radical cation, MV+, in D2O with rate constants k = 1.09 x 10(9) M-1 s-1 and 3.10 x 10(9) M-1 s-1, respectively, at 298 K and 0.050 M ionic strength. The initial chromium(II) products rapidly aquate to yield trans-[Cr([14]aneN4)(H2O)2]2+, which reduces MV2+ back to MV+. This reaction is strongly catalyzed by coordinating anions Cl-, Br-, and SCN-. For X = Cl and Br, the final chromium product is trans-Cr([14]aneN4)(H2O)(X)]2+. The kinetics obey a mixed third-order rate law, k(obs) = k(x)[MV2+] [trans-Cr-([14]aneN4)(H2O)22+][X-1, with k(Cl) = 4.65 x 10(5) M-2 s-1 and k(Br) = 5.22 x 10(5) M-2 s-1 at 298 K and 0.25 M ionic strength. The SCN--catalyzed reaction has a more complex rate law and yields trans-[Cr([14]aneN4)-(NCS)2]+ (NCS)2]+ as the chromium product implying trans-[Cr([14]aneN4)(NCS)2] as the sole kinetically important form of chromium(II). The quenching of trans-[*Cr([14]aneN4)(CN)2]+ by Cr(H2O)62+ (k = 5.23 x 10(7) M-1 s-1), V(H2O)62+ (k = 2.08 X 10(7)), and VO(H2O)52+ (k = 4.54 X 10(6)) takes place by energy transfer.
