Table 1. Thermodynamic Cycles for the Enthalpy of Formation of MB(MeIm)4 Structures, Where M = Cu+ or Li+a.
| Reaction | ΔH (kJ mol–1) |
|---|---|
| 1/2M2O (s, 298 K) + HB(MeIm)4 (s, 298 K) → MB(MeIm)4 (s, 298 K) + 1/2H2O (l, 298 K) | ΔHf = ? |
| MB(MeIm)4 (s, 298 K) → M+ (aq, 298 K) + B(MeIm)4– (aq, 298 K) | ΔH1 |
| M2O (s, 298 K) + 2H+ (aq, 298 K) → 2M+ (aq, 298 K) + H2O (aq, 298 K) | ΔH2 |
| HB(MeIm)4 (s, 298 K) → H+ (aq, 298 K) + B(MeIm)4– (aq, 298 K) | ΔH3 |
| H2O (l, 298 K) → H2O (aq, 298 K) | ΔH4 |
| ΔHf = −ΔH1 + 1/2ΔH2 + ΔH3 – 1/2ΔH4 | ΔHf |
