chloride concentration on extraction have demonstrated that the monoamides in particular show an unusually high selectivity for [ZnCl4]2- over [FeCl4]− and Cl–. Hybrid-DFT calculations on the tri-, di-, and monoamides, L2, L3, and L4, help to rationalize these orders of strength and selectivity. The monoamide L4 has the most favorable protonation energy because formation of the LH+ cation generates a “chelated
