Abstract

A tripodal tris(3-pyridylurea) receptor (L) assembles with metal sulfate salts MSO4 (M = Mn, Zn) to afford supramolecular cages [SO4⊂L2] that encapsulate the SO42− ion via multiple hydrogen bonds in a three-dimensional structure held by second-sphere coordination; 1H NMR and negative-ion mode ESI-MS spectra reveal significantly strong sulfate binding in solution.
