Abstract
In the previous study, 5,5,7,12,12,14–hexamethyl–1,4,8,11–tetraazacyclotetradeca–7,14–dienium diperchlorate, [Me6C10H16N4](ClO4)2 formed complex of C16H34N4OCu(ClO4)2 and C16H32N4Cu(ClO4)2 when reacted with copper(II) acetate monohydrate in acetonitrile and aqueous solutions, respectively. However, when the same reaction carried out in 1–butyl–3– methylimidazolium hexafluorophosphate ionic liquid, [Bmim][PF6], disproportionation took place to give bis(ethylenediamine) bis(perchlorato-O) copper(II) complex, C4H16N4Cu(ClO4)2. X-ray study showed that the central copper atom was coordinated to two ethylenediamine ligands and two oxygen atoms of perchlorate ions in a distorted octahedral environment. Thermogravimetric Analysis (TGA) study showed the complex decomposition in one spontaneous mass loss at 260 oC due to the explosive nature of the perchlorate.
