Incorporation of a dianionic binding site for transition metal cations and a dicationic binding site for anions into a lipophilic molecule has produced a ligand with a high efficacy for the solvent extraction of a transition metal salt [M2+X2–].

salicylaldimine ligands of the H2salen-type bearing ortho-N-morpholinomethyl substituents function as ditopicligands, bonding to NiII or CuII with the [N2O2]2− donor set of the salen unit and a sulfate or two nitrate anions with the protonated morpholine units. The binding of the metal salt by the zwitterionic form of the ligand provides a novel approach to the transport of metal sulfates in metal recovery
