Preparation, characterization, X-ray structure determination and solution properties of some novel copper(I) bisulfate and sulfate salts and their stable derivatives

Abstract

Two highly unstable copper(I) salts, i. e. copper(I) bisulfate tetraacetonitrile, [Cu(CH3CN)4]HSO4, and dicopper(I) sulfate octaacetonitrile, [Cu(CH3CN)4]2SO 4, and their stable derivatives with 2,9-dimethyl-1,10-phenanthroline (DMPhen) have been prepared in pure form and characterized by elemental, spectral and chemical analysis. Single-crystal X-ray studies of [Cu(CH 3CN)4]HSO4 and its derivative [Cu(DMPhen) 2]HSO4 have been carried out. The solution behavior of both of these salts and their derivatives have been investigated using UV/Vis, IR, 63Cu NMR spectroscopy and molar conductance in a number of non-aqueous solvents. Furthermore, a simple method for the preparation of Cu2SO4 is presented. © 2011 Verlag der Zeitschrift für Naturforschung, Tübingen.
