Abstract: | Summary The interaction of copper(II) salts with the imidazole-containing disulphide 5-(1,2,5-dithiazaepan-5-ylmethylene)-4-methyl-2-ethyl imidazole (MAMI) in MeOH have been investigated. The 11 Cu(ClO4)2MAMI system exhibited a single ligand field band at ca. 12200cm-1, an intense shoulder at ca. 31500 cm-1 and a less intense split feature at 24400 and 25300cm-1 assignable to S() CuII and S() CuII charge transfer (CT) transitions, respectively. The e.p.r. parameters suggested the presence of a CuN2SO chromophore, however; the 11 Cu(NO3)2MAMI system did not exhibit a S CuII CT band and the g value was comparatively high. An electrochemical study of the 11 Cu(ClO4)2MAMI system in MeOH revealed that the copper-disulphide interaction, though weaker, would confer a high redox potential as well as reversibility, similar to the copper-thioether interaction. |
