title: Conversion of nonporous helical cadmium organic framework to a porous form.
abstract: Two novel cadmium-organic frameworks containing achiral helical nanotubular channels, [Cd(HImDC)(S)](n) (S = Im(1) and Py(2)), have been synthesized and characterized using single crystal X-ray diffraction, in which 1 converts to 2 upon refluxing 1 in pyridine solution with noticeable porosity and hydrogen uptake at medium pressure.
