A novel iminopyridine-based Zn4L4 tetrahedral cage, synthesized in four steps, binds larger organic anions with binding constants of up to 850 M−1 in MeCN−d3/H2O=9 : 1 and displays stability in basic aqueous acetonitrile. Surprisingly, investigations towards catalysis of reactions with anionic transition states did not indicate rate accelerations in the presence of the cage.
