Abstract
205Tl and1H magnetic resonance frequencies have been determined for liquid ammonia solutions of TlClO4 and TlNO3 as a function of electrolyte concentration (5×10−4 to 9.8 M) and temperature. The dependence of the resonance frequency on concentration suggests the presence of free, fully solvated thallium ions, ion pairs, and higher-order ion aggregates. Analysis of lowconcentration205Tl data between 0 and 30°C allowed the determination of TlNO3 ion-pair association constants and thermodynamic parameters (ΔHA=+6.5 kcal-mole−1, ΔSA=+36 e.u.). A preciptous decrease in205Tl resonance frequency was observed for NH3 to TlNO3 mole ratios below 3:1, suggesting the formula (NH3)3Tl+ NO −3 for the fully solvated, contact ion pair.
