title: Double loading of ZnCl(2) by polytopic ligands which co-extract Zn(2+) and tetrachloridozincate.
abstract: Combining cation- and anion-binding functionalities in a salen-type extractant leads to multiple loading of ZnCl(2). Zn(ii) cations are bound by the salen N(2)O(2)(2-) donor set, and chlorozincate anions are associated with protonated pendant amine groups.
