摘要：

Molar conductances of a large number of copper(I) and cobalt(III) complexes, behaving as strong 1:1 electrolytes, have been measured in acetonitrile (AN) and n-nutryonitrile (n-BTN) at 298.15 K. The conductance data have been analyzed by the Shedlovsky method to evaluate Lambda(0) and K-A values of these electrolytes. Limiting ion conductances (lambda(i)(0)) for various ions in AN have been calculated by using transference number data. In n-BTN, where no transference number data is available, such values have been calculated by an indirect method using Bu4NBPh4 as a reference electrolyte. The actual ionic radii (r(i)) for various ions in solution have been calculated using a modified form of Stokes' law. The ionic radii (r(i)) for various complex ions have been compared with the ionic radii of two reference ions, BU4N+ and Ph4B-, which are not solvated in dipolar aprotic solvents, to throw light on the solvation behaviour of these complex ions.
