Preparation of some novel copper(I) complexes and their molar conductances in organic solvents

Abstract

Attempts have been made to prepare some novel copper(I) nitrate, sulfate, and perchlorate complexes. Molar conductances of these complexes have been measured in organic solvents like acetonitrile (AN), acetone (AC), methanol (MeOH), N,N-dimethylformamide (DMF), N,N-dimethylacetamide (DMA), and dimethylsulfoxide (DMSO) at 298 K. The molar conductance data have been analyzed to obtain limiting molar conductances (Λo) and ion association constants (KA) of the electrolytes. The results showed that all these coomplexes are strong electrolytes in all organic solvents. The limiting ionic molar conductances (λ±0) for various ions have been calculated using Bu4NBPh4 as reference electrolyte. The actual radii for copper(I) complex ions are very large and different in different solvents and indicate some solvation effects in each solvent system. © 2009 Verlag der Zeitschrift für Naturforschung, Tübingen.
