Formation of CuI(CH3CN)4ClO4 in the Reactions of Copper(II) Perchlorate with Acetonitrile in the Presence of Sulfur-Containing Organic Compounds

Cu(ClO4)(2)center dot 6H(2)O was shown to react with 2,2'-[propane-1,3-diylbis(thio-2-phenylnemethylidene]-bis(3-pyridylamine) (1) or (5Z)-2-ethoxycarbonylmethyl-(2-pyridylmethylidene)-3,5-dihydro-4H-imidazol-4-one (II) in the presence of CH3CN with the reduction of copper(II) to copper(l) and the formation of the tetrahedral complex Cu-I(CH3CN)(4)ClO4 (III). In the course of the reaction the organic ligands I and If were oxidized to the corresponding sulfoxides.
