摘要：

The preparation and isolation in the solid state of five aryl 1,2,3,5-dithia- and diselenadiazolyls is reported. The structure of the dimer of 4-Cl-C6H4-CN2S2 in the solid state was obtained: monoclinic, C2/c with Z = 8, a = 20.982(10), b = 10.058(3), c = 15.867(6) angstrom, beta = 93.34(4)-degrees, R = 0.066, R(w) = 0.053 for 1099 data. Cyclic voltammetry shows reversible oxidation to a 6 pi cation for all 10 compounds in both CH2Cl2 and CH3CN; reversible reduction to an 8pi anion is observed in CH2Cl2 for all except X = CF3, E = S. The reductions are only quasi-reversible in CH3CN for E = Se. The oxidation process is independent of chalcogen type; the reduction process is found to be about 0.2 V more negative for E = S vs E = Se.
