A zeolitic imidazolate framework material of SOD  topology possessing primarily unsubstituted imidazolate (im) linkers has been synthesized via solvent-assisted linker exchange (SALE) of ZIF-8 . The structure of the new material, SALEM-2 , has been confirmed through 1H NMR, and powder and single-crystal X-ray diffraction. SALEM-2  is the first example of a porous Zn(im)2 ZIF possessing a truly zeolitic topology that can be obtained in bulk quantities. Upon treatment with n-butyllithium, the open analogue exhibits Br�nsted base catalysis that cannot be accomplished by the parent material ZIF-8 . Additionally, it displays a different size cut-off for uptake and release of molecular guests than does ZIF-8 .
