Twenty-two salts of the type p-YC6H4NMe2R(1+) p-XC6H4SO3(1-) were synthesized.R = Me, Et;x = CH3,Cl,Br,NO2; Y = H,Br.These salts exist as ion pair in dilute solutions in octanoic acid.Eight salts were soluble enough to permit measurement of ion-pair dipole moments.Analysis indicates that in the ion pairs, the N(1+) center of the cation is adjacent to one of SO3(1-) oxygen atoms.Preliminary results for infrared S-O streching frequencies in the free anions and ion pairs are consistent with this analysis.A novel concentric spherical dielectric cell is described.
