The
conformational isomers of zeolitic imidazolate frameworks (ZIFs)
can have their own unique porosity and structural stability. We report
that a new sodalite-like ZIF (termed β-ZIF-65(Zn)) is polymorphous
with as the existing ZIF-65(Zn) (Zn(nIm)2, nIm = 2-nitroimidazolate)
but has a different linker conformation in the six-membered rings
of sodalite cages. This conformational isomerism leads to distinctive
permanent porosity for each conformer, which has been verified by
gas adsorption measurements. In addition, variable-temperature X-ray
diffraction analyses indicate that β-ZIF-65(Zn) is more resistant
to displacive phase transitions than ZIF-65(Zn). The activated β-ZIF-65(Zn)
conformer adsorbs 2.8 times more benzene than the activated ZIF-65(Zn)
at P/P0 = 0.3 and 298
K. This work suggests that other types of ZIF conformers can be discovered.
