The ultrasonic velocities of solutions of Bu4NBPh4, Bu4NClO4, [Cu(AN)4]NO3, [Cu(BN)4]NO3,[Cu(Phen)2]NO3, [Cu(DMPhen)2]NO3, [Cu(Bipy)2]NO3 and [Cu(TU)4]NO3 (where AN = acetonitrile,BN = benzonitrile, Phen = 1,10-phenanthroline, DMPhen = 2,9-dimethyl-1,10-phenanthroline, Bipy= 2,2′-bipyridyl and TU = thiourea) were measured in the concentration range 0.03-0.27 M indimethylsulfoxide (DMSO), nitromethane (NM) and binary mixtures of DMSO + NM containing 0,20, 40, 60, 80 and 100 mol% NM at 298 K in the present studies. Using ultrasonic velocity and densitydata, isentropic compressibility (κs) and apparent molal isentropic compressibility (κs,φ) for electrolytesin DMSO + NM mixture have been calculated. Result shows that copper(I) electrolytes show lesssolvation in NM rich regions indicating structure breaking tendency of nitromethane. Extent of solvationin Cu(I) ions decreases in the order: [Cu(AN)4]+ > [Cu(BN)4]+ > [Cu(TU)4]+ > [Cu(DMPhen)2]+> [Cu(Phen)2]+ > [Cu(Bipy)2]+.
