Abstract
AIM OF THE PRESENT WORK Copper (I) salts are unstable in many orgnic solvents. Previous investigations of copper(I) salts are limited only to acetonitrile and its binary mixtures with some organic solvents. Benzonitrile like acetonitrile has also -C -N group attached to the benzene ring system. This solvent like acetonitrile also stabilize copper (I) salts strongly. Moreover, the solubility of copper(I) salts in benzonitrile and its binary mixtures with other organic solvents is much higher as compared to that in acetonitrile. In spite of very favourable properties of benzonitrile, studies of copper salts have never been made in benzonitrile and its binaru mixtures with other organic solvents. The binary mixtures of benzonitrile with acetonitrile and pyridine has a wide range of dielectric constant and viscosity. these solvent systems are very interesting solvent systems for the study of copper(I) salts. Cu+ and Na+ ions have almost some ionic radii (Cu+ = 0.90 A and Na+ = 0.95 A). These ions are expected to have some type of solvation behaviour in many solvents. It has been found that in nitrile solvents and pyridine Cu+ is solvated by a special type of interaction while Na+ is solvated by the normal electrostatic ion-dipole interaction.
