Micropore Decoration with Bidentate Lewis Acids: Spontaneous Assembly of 1,2-Bis(chloromercurio)tetrafluorobenzene

Dimethyl sulfoxide templates the assembly of 1,2-bis(chloromercurio)tetrafluorobenzene (1) into an internally Lewis acidic microporous solid of composition 1 small middle dot(DMSO)(3) (2). The channels of 2 contain both chelated and solvate DMSO molecules (omitted in the drawing for clarity), which can be partly exchanged with water molecules. The hydration-dehydration of the resulting compound is reversible.
