title: Sulfate-templated self-assembly of new M4L6 tetrahedral metal organic cages.
abstract: Six equivalents of N,N'-bis(4-aminobenzyl)urea, 12 equivalents of 2-formylpyridine and four equivalents of FeSO(4) or NiSO(4) undergo subcomponent self-assembly in aqueous solution to form tetrahedral cages around a single, encapsulated sulfate anion.
