A three dimensional porous metal–organic framework [Fe4L6·(DMF)3·(H2O)10] constructed from neutral discrete Fe4L6pyramids [H2L = 1,3-benzodihydroxamix acid]

Abstract
A 3-D porous zeolite-like metal–organic framework surviving guest removal is assembled from a well-defined tetrahedral Fe4L6 cavity by the cooperativity of hydrogen bonds and π–π stacking.
